Answer 1

Answer:

9 is a perfect square because \begin{align*}\sqrt{9}=3\end{align*}. Not all square roots are whole numbers. Many square roots are irrational numbers, meaning there is no rational number equivalent. For example, 2 is the square root of 4 because \begin{align*}2 \times 2 = 4\end{align*}.
