Question

as matrizes A 0110 e B 1001 calcule (A-2B).A

Answer 1

$2*\left[\begin{array}{cccc}1&0&0&1\end{array}\right] = \left[\begin{array}{cccc}2&0&0&2\end{array}\right]$

$\left[\begin{array}{cccc}0&1&1&0\end{array}\right] -\left[\begin{array}{cccc}2&0&0&2\end{array}\right] = \left[\begin{array}{cccc}-2&1&1&-2\end{array}\right]$

$\left[\begin{array}{cccc}-2&1&1&-2\end{array}\right] * \left[\begin{array}{cccc}0&1&1&0\end{array}\right] = 2$
