Introduction

a. \(\sqrt{32}\)

\begin{equation*}
\begin{split}
\sqrt{32}& = \sqrt{16 \times 2}\\\\
\sqrt{32}& = \sqrt{16} \times \sqrt{2}\\\\
\sqrt{32}& = 4\sqrt{2}\\\\\\
\end{split}
\end{equation*}

b. \(\sqrt{720}\)

\begin{equation*}
\begin{split}
\sqrt{720}& = \sqrt{144 \times 5}\\\\
\sqrt{720}& = \sqrt{144} \times \sqrt{5}\\\\
\sqrt{720}& = 12\sqrt{5}
\end{split}
\end{equation*}
