## What is considered a perfect square?

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.

## Does square root give two answers?

It has multiple answers so why do we pick the positive one? if x2=16⟹x=√16 or x=−√16 for respectively the positive and negative solution. This implies that the square root function has a single answer and we must negate its answer to obtain the second solution.

## Is 18 a perfect square?

Is 18 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself.
