Answer 1

Procedure for determining a perfect square.

As we know that,

Square of a number is defined as the result obtained when a number is multiplied by itself once.

Example,

$\Rightarrow$ $4^2=4\times 4$

$\Rightarrow$ $4^2=16$

The square root of a perfect square is always a positive integers.

Like, $49$ is a perfect square because,

$\Rightarrow$ $\sqrt{49}=7$

A number with a square root that is not a whole number is called a non-perfect square.

Like $40$ is not a perfect square. Because,

$\Rightarrow$ $\sqrt{40}=6.3245$
