解答

$$$\left[\begin{array}{cc}{\color{Magenta}\frac{\sqrt{2}}{2}} & {\color{DarkMagenta}\frac{\sqrt{2}}{2}}\end{array}\right]\cdot \left[\begin{array}{c}{\color{Magenta}\frac{\sqrt{2}}{2}}\\{\color{Purple}\frac{\sqrt{2}}{2}}\end{array}\right] = \left[\begin{array}{c}{\color{Magenta}\left(\frac{\sqrt{2}}{2}\right)}\cdot {\color{Magenta}\left(\frac{\sqrt{2}}{2}\right)} + {\color{DarkMagenta}\left(\frac{\sqrt{2}}{2}\right)}\cdot {\color{Purple}\left(\frac{\sqrt{2}}{2}\right)}\end{array}\right] = \left[\begin{array}{c}1\end{array}\right]$$$

答案

$$$\left[\begin{array}{cc}\frac{\sqrt{2}}{2} & \frac{\sqrt{2}}{2}\end{array}\right]\cdot \left[\begin{array}{c}\frac{\sqrt{2}}{2}\\\frac{\sqrt{2}}{2}\end{array}\right] = \left[\begin{array}{c}1\end{array}\right]$$$A
