### What Is the Square Root of 125? | How to Find the Square Root of 125?

The square root of 125 is 11.18 mentioned with a symbol √. The square root of 125 is denoted using 125 is or 1251/2

The square root of a number is determined when a quantity of a number is produced when multiplied by itself or a factor of a number when multiplied by itself gives the original number. In simple terms when a value is multiplied by itself it gives the original number. For a better understanding. The number 5 when multiplied by itself (5 × 5) = 25. The square root for  (√25) is 5.

## Methods to find the square root of 125

To find the square root of any number first the given number is usually checked to determine whether they are a perfect square number or not. The square of the number s is found using the long division method.

For the number with a perfect square, it is easy to find the square roots and it is a bit tough for non-square values. Numbers like 4,9, 16,25, etc., are perfect squares. Numbers that end with 2,3,7 and 8 are not perfect square numbers.

There are three methods to find the square root of a number

• Prime factorization method
• Long division method
• Repeated subtraction

These methods described above do not apply to finding the square root of any number.

### Prime factorization method

The prime factors of 125 = 5×5×5
125 = 5×√5
= 5× 2.236
Hence, √125= 11.18

### Long division method

• Step 1: Find the smallest integer that can divide the number.
• Step 2: Keep following the long division using divisor and dividend.
• Step 3: When the particular number of satisfaction is reached the quotient is the square root of the number.

Find the square root of 125

• Step 1: Find the smallest integer that can divide the number. 1 is the perfect root number that is smaller and closest to 125.
• Step 2: Keep following the long division using divisor and dividend.
• Step 3: When the particular number of satisfaction is reached the quotient is the square root of the number.

Hence, the √125 = 11.180

## Solved examples

Q1: Find the square root of 4 using the prime factorization method

A2: The √125 = 11.180

Q3: What is the square root of 49 using repeated division

1. 49-1 = 48
2. 48-3 = 45
3. 45-5 = 40
4. 40-7 = 33
5. 33-9 = 24
6. 24-11 = 13
7. 13-13 = 0
A3: The √49 = 7.

Q4: What is the square root of 3
A4: The square root of 3 = 1.7320

Q5: What is the square root of 5
A5: The √5 = 2.2360
