Question

Obtenha a matriz A+B​

Answer 1

Explicação passo-a-passo:

$\sf A+B=\left(\begin{array}{ccc} \sf 1& \sf -2& \sf 2 \\ \sf -3& \sf 6& \sf 3 \\ \sf 2& \sf 4& \sf 0\end{array}\right)+\left(\begin{array}{ccc} \sf -2& \sf 1& \sf -2 \\ \sf 0& \sf -4& \sf 2 \\ \sf 1& \sf -3& \sf -4\end{array}\right)$

$\sf A+B=\left(\begin{array}{ccc} \sf 1-2& \sf -2+1& \sf 2-2 \\ \sf -3+0& \sf 6-4& \sf 3+2 \\ \sf 2+1& \sf 4-3& \sf 0-4\end{array}\right)$

$\sf A+B=\left(\begin{array}{ccc} \sf -1& \sf -1& \sf 0 \\ \sf -3& \sf 2& \sf 5 \\ \sf 3& \sf 1& \sf -4\end{array}\right)$
