# Square and square root

A square of an integer is the product of some integer with itself.

Example: let 2 be the number then square of 2 = ${2}^{2}=2\times 2=4$

The square root of a number is a value that, when multiplied by itself, gives the number.

Example: 4 × 4 = 16, so a square root of 16 is 4
