Question

multiplicação de matrizes

Answer 1

$A = \left[\begin{array}{ccc}1&5\\2&0\\-2&1\end{array}\right] * B = \left[\begin{array}{ccc}1&5&6\\6&5&1\\\end{array}\right] 1+30 5+25 6+5</p><p>2+0 10+0 12+0</p><p>-2+6 -10+5 -12+1</p> <p>[tex] C = \left[\begin{array}{ccc}31&30&11\\2&10&12\\4&-5&-11\end{array}\right]$

Soma dos elementos da segunda coluna de C

30+10+(-5)

= 35
