Question

Calcule e some as matrizes.​

Answer 1

Resposta:

Basta somar os termos que estão na mesma posição das duas matrizes:

A)

$\left[\begin{array}{ccc}-3+1&9+3\\6+2&1+4\end{array}\right] = \left[\begin{array}{ccc}-4&12\\8&5\end{array}\right]$

B)

$\left[\begin{array}{ccc}15+4&7+5&-1+3\\9+10&14+1&6-6\end{array}\right] = \left[\begin{array}{ccc}19&12&2\\19&15&0\end{array}\right]$

C)

$\left[\begin{array}{ccc}1+4&3+2&2+8\\0+3&7+0&4+1\\9+3&0-1&5+10\end{array}\right] = \left[\begin{array}{ccc}5&5&10\\3&7&5\\12&-1&15\end{array}\right]$

D)

$\left[\begin{array}{ccc}1+2&0-5&0+0\\0+8&1-1&0+7\\0+4&0+3&1+2\end{array}\right] =\left[\begin{array}{ccc}3&-5&0\\8&0&7\\4&3&3\end{array}\right]$

Confira as contas, bons estudos. :)
