What's the square root of 4?

The square of a number is when a number is multiplied by itself i.e 3^2= 3 * 3 = 9. Now square root of a number is the original number, i.e. the number which was multiplied by itself, for example the square root of 9 will be 3.

In the same way the square root of 4 is **2** i.e. 2 * 2 = 4.

Square root is basically a number that when multiplied by itself, we get the number in the root. Like;

`sqrt25=5`

`sqrt100=10`

`sqrt9=3`

`sqrt36=6`

Hence like above the square root of 25 is 5. That is the number 5 when multiplied to itself we get 25. Same explanation is for all examples.

`sqrt4=sqrt(2*2)`

`sqrt4=2`

**Hence in the same way the square root of 4 is 2.**

Hope you understand.

The square root of 4 is 2 . You can basically think of it as 2 × 2 .

Other examples of square roots are :

The square root of 36 is 6 .

The square root of 25 is 5 .

The square root of 49 is 7 .

The square root of 64 is 8 .

2 because 2x2 is 4, the square root of a number is a number that can be multiplied by itself to get the result for example the square root of 16 is 4 because 4x4=16

The square root of 4 is 2.

To check this, square the result (i.e 2) and check if it matches the original number.
