Simplifying the square root involves expressing it in its simplest radical form, which is particularly useful in various mathematical contexts. Here, we will explore the steps to simplify the square root of 117 and discuss its significance.

First, recognize that 117 is not a perfect square, meaning its square root will not be an integer. We use the prime factorization method to simplify the square root:

  1. Find the prime factors of 117, which are 3, 3, and 13. Thus, 117 can be expressed as 3² * 13.
  2. Rewrite the square root of 117 as the product of the square roots of its prime factors: √117 = √(3² * 13).
  3. Since the square root of a product is the product of the square roots, we get: √(3² * 13) = √(3²) * √13.
  4. The square root of 3² is 3, so we simplify this to: 3√13.

This simplification is useful for mathematical problem-solving and provides a clearer understanding of the properties of the number 117.

Prime Factorization Method

To simplify the square root of 117 using the prime factorization method, follow these detailed steps:

  1. First, find the prime factors of 117. Start by dividing 117 by the smallest prime number, which is 2. Since 117 is not divisible by 2, move to the next prime number, 3.
  2. Divide 117 by 3:

    117 ÷ 3 = 39

    39 is also divisible by 3:

    39 ÷ 3 = 13

    13 is a prime number.

  3. Thus, the prime factorization of 117 is:
    117 = 3 × 3 × 13
  4. Group the prime factors into pairs:

    (3 × 3) and 13

  5. Take one factor from each pair and multiply them:

    √117 = √(3² × 13) = 3√13

Therefore, the simplified form of the square root of 117 is 3√13.
