Rational or Irrational Number?


To determine whether the square root of 164 is a rational or irrational number, we need to understand the definitions of these types of numbers. A rational number can be expressed as a fraction of two integers, where the denominator is not zero. An irrational number cannot be expressed as a simple fraction.


The square root of 164 is represented as √164. To check if this is a rational number, we need to see if 164 is a perfect square. A perfect square is a number that can be expressed as the product of an integer with itself.


For example:

  • 4 is a perfect square because it is 2×2.
  • 9 is a perfect square because it is 3×3.


Now, let's examine 164:

  1. Check for factors of 164: 164 = 2 × 82.
  2. Further factor 82: 82 = 2 × 41.


Therefore, the prime factorization of 164 is 2 × 2 × 41. Since there is no repeated factor that can form a pair, 164 is not a perfect square. As a result, √164 cannot be simplified to a whole number or a fraction of two integers, making it an irrational number.


In conclusion, since 164 is not a perfect square, the square root of 164 (√164) is an irrational number, meaning it cannot be written as a simple fraction and its decimal representation is non-terminating and non-repeating.

Exponent Representation

Exponent representation of square roots involves expressing the square root of a number as an exponent. This method is useful for simplifying and solving various mathematical problems.

The square root of a number \(x\) can be represented as \(x^{\frac{1}{2}}\). Using this rule, we can express the square root of 164 in exponent form.

Here are the steps to represent the square root of 164 using exponents:

  1. Identify the base number: In this case, the base number is 164.
  2. Apply the exponent rule: The square root of 164 can be written as \(164^{\frac{1}{2}}\).

Thus, the exponent representation of the square root of 164 is \(164^{\frac{1}{2}}\).

Let's break this down further with the help of MathJax:

\[
\sqrt{164} = 164^{\frac{1}{2}}
\]

We can also consider the properties of exponents for more complex operations involving the square root of 164:

  • Division: When dividing two square roots, we subtract their exponents. For example, \[ \frac{\sqrt{164}}{\sqrt{164}} = 164^{\frac{1}{2}} \div 164^{\frac{1}{2}} = 164^{0} = 1 \]
  • Exponentiation: When raising a square root to another exponent, we multiply the exponents. For example, \[ (\sqrt{164})^2 = (164^{\frac{1}{2}})^2 = 164^{1} = 164 \]

Understanding the exponent representation of square roots is essential for simplifying expressions and solving equations involving radicals. This approach is widely used in algebra, calculus, and higher-level mathematics.

Exponent Representation

Long Division Method

The long division method is a reliable and precise technique to find the square root of a number. Below are the detailed steps to find the square root of 164 using this method:

  1. Pair the Digits: Starting from the decimal point and moving both left and right, pair the digits of the number. For 164, we pair as (01)(64)(00).
  2. Find the Largest Square: Determine the largest number whose square is less than or equal to the first pair. For the first pair (01), the largest square is 1 (since \(1^2 = 1\)). Place 1 as the first digit of the quotient.
  3. Subtract and Bring Down: Subtract the square of the quotient from the first pair and bring down the next pair. Subtracting \(1\) from \(1\) gives \(0\), then bring down (64) to get (064).
  4. Double the Quotient and Find the Next Digit: Double the current quotient (1) to get 2. Find the largest digit (X) such that \(2X \times X \leq 64\). Here, \(22 \times 2 = 44\) is the closest, so the next digit is 2.
  5. Repeat: Repeat the process:
    • Subtract \(44\) from \(64\) to get \(20\).
    • Bring down the next pair (00) to get \(2000\).
    • Double the quotient (12) to get 24. Find the largest X such that \(24X \times X \leq 2000\). Here, \(248 \times 8 = 1984\) is the closest, so the next digit is 8.
    • Subtract \(1984\) from \(2000\) to get \(16\).
  6. Continue for More Precision: Continue this process as needed to achieve the desired decimal places. For 164, repeating these steps gives a quotient of approximately \(12.806\).

Therefore, using the long division method, the square root of 164 is approximately \(12.806\).

This detailed method provides a clear and systematic way to determine the square root of 164 using long division.

Solved Examples and Applications

Understanding the square root of 164 through solved examples and applications helps illustrate its practical uses. Here are some scenarios where the square root of 164 is applied:

Example 1: Determining the Length of a Room

Mike wants to cover his room's floor with tiles and needs to know the floor dimensions. The floor is square-shaped with an area of 164 square feet. What will be the length of the room's floor? Round your answer to the nearest tenth.

  1. Let the length of the room be \( x \) feet. Therefore, the area of the room's floor is \( x^2 \) square feet.
  2. Given: \( x^2 = 164 \)
  3. Taking the square root of both sides: \( x = \sqrt{164} \approx 12.806 \)
  4. Rounding to the nearest tenth: \( x \approx 12.8 \) feet

Thus, the length of the room is approximately 12.8 feet.

Example 2: Finding the Radius of a Circular Park

What is the radius of a circular park having an area of \( 328\pi \) square feet?

  1. Use the formula for the area of a circle: \( \pi r^2 = 328\pi \)
  2. Divide both sides by \( \pi \): \( r^2 = 328 \)
  3. Taking the square root of both sides: \( r = \sqrt{328} = \sqrt{164 \times 2} = \sqrt{164} \times \sqrt{2} \approx 12.8 \times 1.414 \approx 18.1 \)

Therefore, the radius of the park is approximately 18 feet.

Example 3: Length of a Side of an Equilateral Triangle

If the area of an equilateral triangle is \( 164\sqrt{3} \) square inches, find the length of one of the sides.

  1. Let \( a \) be the length of one side of the triangle. The area of an equilateral triangle is given by \( \frac{\sqrt{3}}{4} a^2 \).
  2. Set up the equation: \( \frac{\sqrt{3}}{4} a^2 = 164\sqrt{3} \)
  3. Divide both sides by \( \sqrt{3} \): \( \frac{1}{4} a^2 = 164 \)
  4. Multiply both sides by 4: \( a^2 = 656 \)
  5. Taking the square root of both sides: \( a = \sqrt{656} = \sqrt{4 \times 164} = 2\sqrt{164} \approx 2 \times 12.806 = 25.612 \) inches

Hence, the length of one side of the equilateral triangle is approximately 25.6 inches.
