Introduction to Square Roots

Square roots are a fundamental concept in mathematics, representing a value that, when multiplied by itself, gives the original number. The square root is denoted by the radical symbol \(\sqrt{}\). For example, the square root of 9 is 3, because \(3 \times 3 = 9\).

Key points about square roots:

  • The square root of a number \(x\) is written as \(\sqrt{x}\).
  • Square roots can be positive or negative, but by convention, we refer to the principal (positive) square root.
  • Perfect squares, such as 1, 4, 9, 16, and 25, have whole number square roots.
  • Non-perfect squares, such as 2, 3, 5, and 89, result in irrational numbers when square rooted.

Calculating the square root of a number can be done using various methods:

  1. Prime Factorization: Breaking down the number into its prime factors can help simplify square roots, especially for perfect squares.
  2. Long Division Method: A manual method for finding the square root of a number, useful for non-perfect squares.
  3. Approximation: Using a calculator or numerical methods to find the approximate value of a square root.

In the case of prime numbers like 89, the square root does not simplify into a smaller radical form. Thus, the square root of 89 remains as \(\sqrt{89}\).

Understanding square roots is crucial in various fields, including algebra, geometry, and applied sciences, as it lays the foundation for solving equations, analyzing shapes, and interpreting scientific data.

Understanding the Square Root of 89

The square root of 89, denoted as \(\sqrt{89}\), is an irrational number. This means it cannot be expressed as a simple fraction and its decimal representation is non-terminating and non-repeating.

Here is a step-by-step approach to understanding and simplifying the square root of 89:

This understanding is crucial for various mathematical applications, including solving equations and performing calculations that involve square roots.

Prime Factorization of 89

Prime factorization is the process of breaking down a number into its smallest prime factors. To understand the prime factorization of 89, we need to determine whether it can be divided by any prime numbers other than 1 and itself.

  1. Identifying Primes:

    First, we list the prime numbers less than 89: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83.

  2. Testing Divisibility:

    We test each prime number to see if it divides 89 without leaving a remainder:

    • 89 is not divisible by 2 (since 89 is odd).
    • 89 is not divisible by 3 (sum of digits, 8 + 9 = 17, which is not divisible by 3).
    • 89 is not divisible by 5 (since it does not end in 0 or 5).
    • 89 is not divisible by 7 (89 ÷ 7 ≈ 12.714).
    • Continuing this process for all primes up to the square root of 89 (approximately 9.434) shows that 89 is not divisible by any of these primes.
  3. Conclusion:

    Since 89 is not divisible by any prime numbers other than itself, we conclude that 89 is a prime number. Its prime factorization is simply:


    \[
    89 = 89 \times 1
    \]

In summary, 89 is a prime number and its prime factorization is trivial. This understanding helps us in simplifying expressions involving \(\sqrt{89}\), confirming that it cannot be simplified further due to the lack of smaller prime factors.

Why 89 is a Prime Number

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. To determine why 89 is a prime number, we need to check if it can be divided evenly by any numbers other than 1 and 89.

Here is a step-by-step explanation:

  1. Definition of Prime Numbers:

    A prime number is only divisible by 1 and itself. For example, 2, 3, 5, and 7 are prime numbers because they do not have divisors other than 1 and themselves.

  2. Checking for Factors:

    To determine if 89 is a prime number, we test its divisibility by all prime numbers less than or equal to the square root of 89 (approximately 9.434). These primes are 2, 3, 5, and 7.

    • Divisibility by 2: 89 is odd, so it is not divisible by 2.
    • Divisibility by 3: The sum of the digits of 89 is 8 + 9 = 17. Since 17 is not divisible by 3, neither is 89.
    • Divisibility by 5: Numbers ending in 0 or 5 are divisible by 5. Since 89 ends in neither, it is not divisible by 5.
    • Divisibility by 7: Dividing 89 by 7 gives approximately 12.714, which is not an integer. Therefore, 89 is not divisible by 7.
  3. Conclusion:

    Since 89 is not divisible by any prime numbers up to its square root, it has no divisors other than 1 and itself. Thus, 89 is confirmed to be a prime number.


    \[
    89 = 1 \times 89
    \]

In summary, 89 is a prime number because it cannot be divided evenly by any other numbers except for 1 and 89. Understanding the primality of 89 is essential for simplifying expressions involving \(\sqrt{89}\) and for various mathematical applications.

Methods to Simplify Square Roots

Simplifying square roots involves expressing the root in its simplest radical form. Here are the detailed methods to simplify square roots:

  1. Prime Factorization:

    Break down the number under the square root into its prime factors and pair the prime factors.

    • Example: Simplify \(\sqrt{72}\).
    • Prime factorization of 72 is \(2 \times 2 \times 2 \times 3 \times 3\).
    • Pair the prime factors: \( (2 \times 2) \) and \( (3 \times 3) \) and \(2\) remains unpaired.
    • Thus, \(\sqrt{72} = \sqrt{(2 \times 2) \times (3 \times 3) \times 2} = 2 \times 3 \times \sqrt{2} = 6\sqrt{2}\).
  2. Simplification Using Perfect Squares:

    Identify and extract the largest perfect square factor of the number under the square root.

    • Example: Simplify \(\sqrt{50}\).
    • The largest perfect square factor of 50 is 25.
    • Thus, \(\sqrt{50} = \sqrt{25 \times 2} = \sqrt{25} \times \sqrt{2} = 5\sqrt{2}\).
  3. Rationalizing the Denominator:

    When a square root appears in the denominator, multiply the numerator and the denominator by the same square root to rationalize.

    • Example: Simplify \(\frac{1}{\sqrt{3}}\).
    • Multiply by \(\sqrt{3}/\sqrt{3}\): \(\frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}\).
  4. Using Algebraic Identities:

    Utilize algebraic identities to simplify square roots involving sums or differences.

    • Example: Simplify \(\sqrt{a^2 + 2ab + b^2}\).
    • Recognize the identity: \((a + b)^2 = a^2 + 2ab + b^2\).
    • Thus, \(\sqrt{a^2 + 2ab + b^2} = \sqrt{(a + b)^2} = |a + b|\).

In summary, simplifying square roots can be done through various methods including prime factorization, using perfect squares, rationalizing the denominator, and applying algebraic identities. Each method provides a systematic approach to expressing square roots in their simplest form.
