Answer 1

Resposta:

C= $\left[\begin{array}{ccc}6&5&39\\3&-62&14\\1&34&11\end{array}\right]$                              D=  $\left[\begin{array}{ccc}4&5&29\\15&-72&-10\\-1&18&-9\end{array}\right]$

Explicação passo-a-passo:

C= A+B =  $\left[\begin{array}{ccc}5&5&34\\9&-67&2\\0&26&1\end{array}\right] + \left[\begin{array}{ccc}1&0&5\\-6&5&12\\1&8&10\end{array}\right]$

C=    $\left[\begin{array}{ccc}5+1&5+0&34+5\\9+(-6)&(-67)+5&2+12\\0+1&26+8&1+10\end{array}\right]$

C= $\left[\begin{array}{ccc}6&5&39\\3&-62&14\\1&34&11\end{array}\right]$

D= A - B =    $\left[\begin{array}{ccc}5&5&34\\9&-67&2\\0&26&1\end{array}\right] - \left[\begin{array}{ccc}1&0&5\\-6&5&12\\1&8&10\end{array}\right]$

D= $\left[\begin{array}{ccc}5-1&5-0&34-5\\9-(-6)&(-67)-5&2-12\\0-1&26-8&1-10\end{array}\right]$

D= $\left[\begin{array}{ccc}4&5&29\\15&-72&-10\\-1&18&-9\end{array}\right]$
