解答
$$$\left[\begin{array}{c}{\color{Chocolate}2 \sqrt{2}}\\{\color{GoldenRod}2 \sqrt{2}}\end{array}\right]\cdot \left[\begin{array}{cc}{\color{Purple}2 \sqrt{2}} & {\color{DarkMagenta}2 \sqrt{2}}\end{array}\right] = \left[\begin{array}{cc}{\color{Chocolate}\left(2 \sqrt{2}\right)}\cdot {\color{Purple}\left(2 \sqrt{2}\right)} & {\color{Chocolate}\left(2 \sqrt{2}\right)}\cdot {\color{DarkMagenta}\left(2 \sqrt{2}\right)}\\{\color{GoldenRod}\left(2 \sqrt{2}\right)}\cdot {\color{Purple}\left(2 \sqrt{2}\right)} & {\color{GoldenRod}\left(2 \sqrt{2}\right)}\cdot {\color{DarkMagenta}\left(2 \sqrt{2}\right)}\end{array}\right] = \left[\begin{array}{cc}8 & 8\\8 & 8\end{array}\right]$$$
