Votre saisie
Calculer $$$\frac{\left[\begin{array}{cc}2 \sqrt{2} & 2 \sqrt{2}\end{array}\right]}{4}$$$.
Solution
Multipliez chaque élément de la matrice par le scalaire :
$$${\color{Blue}\left(\frac{1}{4}\right)}\cdot \left[\begin{array}{cc}2 \sqrt{2} & 2 \sqrt{2}\end{array}\right] = \left[\begin{array}{cc}{\color{Blue}\left(\frac{1}{4}\right)}\cdot \left(2 \sqrt{2}\right) & {\color{Blue}\left(\frac{1}{4}\right)}\cdot \left(2 \sqrt{2}\right)\end{array}\right] = \left[\begin{array}{cc}\frac{\sqrt{2}}{2} & \frac{\sqrt{2}}{2}\end{array}\right]$$$
Réponse
$$$\frac{\left[\begin{array}{cc}2 \sqrt{2} & 2 \sqrt{2}\end{array}\right]}{4} = \left[\begin{array}{cc}\frac{\sqrt{2}}{2} & \frac{\sqrt{2}}{2}\end{array}\right]\approx \left[\begin{array}{cc}0.707106781186548 & 0.707106781186548\end{array}\right]$$$A
