How to Find Square Root and Square Relationship

The square root of a number is simply the inverse operation of squaring that number. In other words, the square of a number is that number times itself.

For example,

since 2^2 =4, the square root of 4 is therefore 2;           (`sqrt(4)` =2)

since 3^2=9, the square root of 9 is therefore 3;

since 4^2=16, the square root of 16 is therefore 4;

etc...

 

Basic on what we have discussed, it's not difficult to conclude that the square root of the square of the number is just the same number. For example:

`sqrt(2^2)` =2

`sqrt(3^2)` =3

etc...
