Answer 1

Olá!

Resolvendo:

$Q = M - N$

$Q = \left[\begin{array}{ccc}2&-1&3\\2&1&1\\3&4&5\end{array}\right] -\left[\begin{array}{ccc}-2&3&3\\-2&2&-2\\3&1&0\end{array}\right]$

$Q = \left[\begin{array}{ccc}2-(-2)&-1-3&3-3\\2-(-2)&1-2&1-(-2)\\3-3&4-1&5-0\end{array}\right]$

$Q = \left[\begin{array}{ccc}4&-4&0\\4&-1&3\\0&3&5\end{array}\right] \end{array}}\qquad\quad\checkmark$

Espero ter ajudado!
