Great! Can you explain the concept of perfect squares to me?
A perfect square is a number that can be expressed as the product of a non-negative integer multiplied by itself. For example, 4 is a perfect square because it can be written as 2 multiplied by 2. 9, 16, 25, and so on are also perfect squares.
