These forms are used in various mathematical applications, including geometry and algebra, where precise or simplified values are needed.

There are several methods to calculate the square root of 60. Below are the most common methods:

• Prime Factorization Method
  1. First, factorize 60 into its prime factors: \( 60 = 2^2 \times 3 \times 5 \).
  2. Group the prime factors into pairs: \( \sqrt{60} = \sqrt{2^2 \times 3 \times 5} \).
  3. Extract the pairs out of the square root: \( \sqrt{60} = 2\sqrt{15} \).
  4. Thus, the simplified radical form is \( 2\sqrt{15} \).
• Long Division Method
  1. Start by grouping the digits in pairs from right to left. For 60, consider 60.00 for more precision.
  2. Find the largest number whose square is less than or equal to 60. In this case, it’s 7 because \( 7^2 = 49 \).
  3. Subtract 49 from 60 to get the remainder 11. Bring down two zeros to get 1100.
  4. Double the divisor (7), making it 14. Find a digit (X) such that \( 14X \times X \leq 1100 \). This gives us 7 because \( 147 \times 7 = 1029 \).
  5. Repeat this process to get a more accurate value, continuing with 7100 and so on. The approximate value up to two decimal places is 7.74.
