Question

Me ajude, por favor !!!!

Answer 1

Explicação passo a passo:

A = $\left[\begin{array}{cc}2&37&1&49\end{array}\right]$  B = $\left[\begin{array}{cc}36&-4&17&2\end{array}\right]$  C = $\left[\begin{array}{ccc}5&3&1\\8&9&0\\4&6&2\end{array}\right]$

1) A + B:

$\left[\begin{array}{cc}2+36&37+(-4)&1+17&49+2\end{array}\right]$

$\left[\begin{array}{cc}38&33&18&51\end{array}\right]$

2) A - B:

$\left[\begin{array}{cc}2-36&37-(-4)&1-17&49-2\end{array}\right]$

$\left[\begin{array}{cc}-34&41&-16&47\end{array}\right]$

3) 3C:

$\left[\begin{array}{ccc}5*3&3*3&1*3\\8*3&9*3&0*3\\4*3&6*3&2*3\end{array}\right]$

$\left[\begin{array}{ccc}15&9&3\\24&27&0\\12&18&6\end{array}\right]$
