Calculate $$$\left[\begin{array}{c}2 \sqrt{2}\\2 \sqrt{2}\end{array}\right]\cdot \left[\begin{array}{cc}2 \sqrt{2} & 2 \sqrt{2}\end{array}\right].$$$
Solution
$$$\left[\begin{array}{c}{\color{Fuchsia}2 \sqrt{2}}\\{\color{Violet}2 \sqrt{2}}\end{array}\right]\cdot \left[\begin{array}{cc}{\color{DeepPink}2 \sqrt{2}} & {\color{Crimson}2 \sqrt{2}}\end{array}\right] = \left[\begin{array}{cc}{\color{Fuchsia}\left(2 \sqrt{2}\right)}\cdot {\color{DeepPink}\left(2 \sqrt{2}\right)} & {\color{Fuchsia}\left(2 \sqrt{2}\right)}\cdot {\color{DeepPink}\left(2 \sqrt{2}\right)}\\{\color{Fuchsia}\left(2 \sqrt{2}\right)}\cdot {\color{DeepPink}\left(2 \sqrt{2}\right)} & {\color{Fuchsia}\left(2 \sqrt{2}\right)}\cdot {\color{DeepPink}\left(2 \sqrt{2}\right)}\end{array}\right] = \left[\begin{array}{cc}8 & 8\\8 & 8\end{array}\right]$$$
Answer
$$$\left[\begin{array}{c}2 \sqrt{2}\\2 \sqrt{2}\end{array}\right]\cdot \left[\begin{array}{cc}2 \sqrt{2} & 2 \sqrt{2}\end{array}\right] = \left[\begin{array}{cc}8 & 8\\8 & 8\end{array}\right]$$$A
