Question

Dada a matriz:
A= 5 7
9 4

B= 6 -2
5 8
Encontre A+B.

Answer 1

Você soma coordenada por coordenada:

A+B =$\left[\begin{array}{ccc}5&7\\9&4\end{array}\right]$ + $\left[\begin{array}{ccc}6&-2\\5&8\end{array}\right]$ = $\left[\begin{array}{ccc}5+6&7+(-2)\\9+5&4+8\end{array}\right]$ = $\left[\begin{array}{ccc}11&5\\\14&12\\\end{array}\right]$ .

Espero ter ajudado, bjs!
