Prime Factorization Method

The prime factorization method is a useful way to find the square root of a number by breaking it down into its prime factors. Let's go through the steps to find the square root of 24 using this method:

  1. Find the prime factors of 24.
    • 24 = 2 × 2 × 2 × 3
  2. Pair similar prime factors.
    • 24 = 2² × 2 × 3
  3. Take the square root of each pair and multiply them.

  4. Simplify the result.
    • \(\sqrt{24} \approx 2 \times 2.449 \approx 4.898\)

Therefore, the square root of 24, using the prime factorization method, is approximately 4.898.

Prime Factorization Method

Long Division Method

The long division method is a manual technique to find the square root of a number. Here is a step-by-step guide to find the square root of 24 using this method:

  1. First, pair the digits of the number from right to left. Since 24 has only two digits, it remains as 24.

  2. Find the largest number whose square is less than or equal to the first pair. The largest number whose square is less than 24 is 4, because \(4^2 = 16\). Write 4 as the first digit of the square root.

  3. Subtract the square of 4 from the first pair: 24 - 16 = 8. Bring down the next pair of digits (in this case, 00, because we have no more digits). Now we have 800.

  4. Double the number already found in the quotient (4), which gives us 8. Write this number as a divisor, leaving a blank space next to it: 8_. Now we need to find a digit (X) such that \(8X \times X \leq 800\).

  5. Try 8: \(88 \times 8 = 704\), which is less than 800. So, we write 8 in the quotient, giving us 4.8.

  6. Subtract \(704\) from \(800\), leaving a remainder of 96. Bring down another pair of zeros, making it 9600.

  7. Double the part of the quotient found so far (48), giving us 96. Write this as the new divisor, leaving a blank space: 960_. Find a digit (Y) such that \(960Y \times Y \leq 9600\).

  8. Try 9: \(9609 \times 9 = 86481\), which is too large. Try 8: \(9608 \times 8 = 76864\), which is less than 9600. Write 8 in the quotient, giving us 4.88.

  9. Subtract \(76864\) from \(9600\), leaving a remainder. Repeat the process to get more decimal places as needed.

Therefore, the square root of 24 using the long division method is approximately 4.88, accurate to two decimal places. Continue the process to obtain more precise values.

Using Calculators for Square Root

  2. Enter the number 24 into the calculator. This can be done by pressing the digits 2 and 4 in sequence.

  3. Press the square root button (\(\sqrt{}\) or "sqrt"). On many calculators, this will immediately display the square root of the entered number. If your calculator requires an additional step, you might need to press the "=" or "Enter" button.

  4. Read the result displayed on the calculator screen. The square root of 24 will be shown as approximately 4.89898. This is a rounded decimal representation.

  5. For more precision, you can use a scientific calculator or an online calculator that allows for more decimal places. Many online calculators also provide the option to view the result in different formats, such as fractional or exponential forms.

Geometric Applications

The square root of 24 has several interesting applications in geometry. Below, we explore some key examples:

1. Calculating the Length of a Diagonal

In a rectangle, the diagonal can be found using the Pythagorean theorem. If one side is \( a \) and the other side is \( b \), the diagonal \( d \) is given by:

\[
d = \sqrt{a^2 + b^2}
\]

Consider a rectangle with sides 4 and 2√6. The diagonal is:

\[
d = \sqrt{4^2 + (2\sqrt{6})^2} = \sqrt{16 + 24} = \sqrt{40} = 2\sqrt{10}
\]

2. Area of an Equilateral Triangle

The area \( A \) of an equilateral triangle with side length \( s \) can be calculated using:

\[
A = \frac{\sqrt{3}}{4} s^2
\]

If the side length is \( 2\sqrt{6} \), the area is:

\[
A = \frac{\sqrt{3}}{4} (2\sqrt{6})^2 = \frac{\sqrt{3}}{4} \times 24 = 6\sqrt{3}
\]

3. Volume of a Cube

The volume \( V \) of a cube with side length \( s \) is given by:

\[
V = s^3
\]

If the side length is \( \sqrt{24} \), the volume is:

\[
V = (\sqrt{24})^3 = 24\sqrt{24}
\]

4. Constructing Right-Angled Triangles

The square root of 24 is useful in constructing right-angled triangles. If one leg of a right-angled triangle is \( \sqrt{24} \) and the other is 6, the hypotenuse \( c \) is:

\[
c = \sqrt{(\sqrt{24})^2 + 6^2} = \sqrt{24 + 36} = \sqrt{60} = 2\sqrt{15}
\]

5. Inscribing a Circle in a Square

If a circle is inscribed in a square with an area of 24 square units, the diameter of the circle is the side length of the square. Thus, the side length \( s \) is:

\[
s = \sqrt{24}
\]

Hence, the radius \( r \) of the circle is:

\[
r = \frac{\sqrt{24}}{2}
\]

These examples illustrate the versatility of the square root of 24 in various geometric contexts, enhancing our understanding of shapes, areas, and volumes.

Rational Approximations

Approximating the square root of 24 using rational numbers can be helpful when an exact value is not necessary or when working without a calculator. Here are some methods to find rational approximations for the square root of 24:

Method 1: Using Perfect Squares

To find a rational approximation, we can start by identifying perfect squares close to 24:

  • The perfect square less than 24 is \(4^2 = 16\)
  • The perfect square greater than 24 is \(5^2 = 25\)

Thus, we know that:

\[ 4 < \sqrt{24} < 5 \]

Method 2: Averaging Method

We can refine the approximation by averaging numbers within the interval:

  1. Start with the interval [4, 5]
  2. Calculate the midpoint: \(\frac{4 + 5}{2} = 4.5\)
  3. Square the midpoint: \(4.5^2 = 20.25\)
  4. Since \(20.25 < 24\), the square root of 24 is closer to 5 than to 4.5

Next, refine the interval [4.5, 5]:

  1. Midpoint: \(\frac{4.5 + 5}{2} = 4.75\)
  2. Square the midpoint: \(4.75^2 = 22.5625\)
  3. Since \(22.5625 < 24\), the square root of 24 is closer to 5 than to 4.75

Continue this process to get more accurate approximations.

Method 3: Using the Formula for Better Approximation

Another method involves using a formula to approximate square roots:

Let \( n = 24 \), \( p = 16 \) (largest perfect square less than 24), and \( q = 8 \) (since \( 24 - 16 = 8 \)). The formula is:

\[\sqrt{n} \approx \sqrt{p} + \frac{q}{2\sqrt{p} + 1}\]

Substitute the values:

\[\sqrt{24} \approx 4 + \frac{8}{2(4) + 1} = 4 + \frac{8}{9} \approx 4 + 0.89 \approx 4.89\]

Thus, a rational approximation for the square root of 24 is approximately 4.89.

Decimal Approximations

Using decimal approximations, we often round to a certain number of decimal places. The square root of 24 is approximately 4.898979485. For practical purposes, it can be rounded to:

  • 1 decimal place: 4.9
  • 2 decimal places: 4.90
  • 3 decimal places: 4.899

These methods provide ways to find rational approximations for the square root of 24, which can be useful in various mathematical calculations and applications.

Rational Approximations

Irrational Numbers and Their Properties

An irrational number is a real number that cannot be expressed as a ratio of two integers. This means it cannot be written in the form p/q, where p and q are integers and q ≠ 0. The square root of 24, denoted as \(\sqrt{24}\), is an example of an irrational number.

Irrational numbers have several key properties:

  • Non-terminating and Non-repeating Decimal Expansion: The decimal form of an irrational number never ends and does not repeat in a pattern. For instance, the decimal representation of \(\sqrt{24}\) is approximately 4.898979485566356, and it continues without repeating.
  • Inclusion in the Real Number System: Irrational numbers are part of the real numbers. Together with rational numbers, they complete the set of real numbers, denoted as \(\mathbb{R}\).
  • Algebraic and Transcendental Types: Irrational numbers can be classified as algebraic or transcendental. Algebraic irrationals are roots of non-zero polynomial equations with rational coefficients, such as \(\sqrt{24}\). Transcendental numbers, like π and e, are not roots of any such polynomial.
  • Closure Under Addition and Multiplication: The sum or product of a rational number and an irrational number is irrational. However, the sum or product of two irrational numbers can be rational or irrational.

Understanding these properties helps in various fields of mathematics and practical applications where precise calculations are essential.
