Before we dive into whether 16 is a perfect square, let’s first understand what a perfect square is. A perfect square is a number that you get when you multiply a whole number by itself. In simpler words, you have a number that can be written as another number times itself, that first number is called a perfect square.

For example:

4 x 4 = 16

3 x 3 = 9

5 x 5 = 25

In these examples, 16, 9 and 25 are perfect squares.

## Is 16 a perfect square?

Let’s check if 16 is a perfect square by following these simple steps:
