## How Does Square Root Calculator Work?

The square root of a number is a number that, when multiplied by itself, gives the product as the original number. '√ ' is the symbol that is used to represent the square root of a number. There are four methods to find the square root of a number. These are listed as follows:

- Repeated subtraction method.
- Prime Factorization method.
- Estimation Method.
- Long Division Method.

The first three methods are very useful in determining the square root of a perfect square. A positive number that can be written as the multiplication of the number by itself can be defined as a perfect square. The long division method is more laborious however, it can be used in finding the square root of any number. Such a number does not have to be a perfect square. If the unit's place of a number has 2, 3, 7, or 8 then the perfect square root will not exist. However, if the unit's place of a number has 1, 4, 5, 6, or 9 then such a number can have a perfect square root. The formula for a square root is given as

y = √x

## Solved Examples on Square Root Calculator

**Example 1:**

Find the square root of 64 and verify it using the square root calculator.

**Solution:**

Using the Prime Factorization Method

64 = 2 × 2 × 2 × 2 × 2 × 2

64 = 2^{2} × 2^{2} × 2^{2}

64 = (2 × 2 × 2)^{2}

64 = 8^{2}

√64 = 8

Therefore, 8 is the square root 64.

**Example 2:**

Find the square root of 25 and verify it using the square root calculator.

**Solution:**

Using the Prime Factorization Method

25 = 5 × 5

25 = 5^{2}

√25 = 5

Therefore, 5 is the square root 25.
