Answer 1

Explicação passo-a-passo:

$A=\left[\begin{array}{cccc}5&-4&0&3\\6&10&8&7\\1&2&-5&-1\end{array}\right] \\\\A=\left[\begin{array}{cccc}a_{11} &a_{12} &a_{13} &a_{14} \\a_{21} &a_{22} &a_{23} &a_{24} \\a_{31} &a_{32} &a_{33} &a_{34} \end{array}\right]$

a)$a_{34}=-1$

b)$a_{22}=10$

c)$a_{13} =0$

d)

$a_{31}+a_{24} =1+7\\\\a_{31}+a_{24}=8$
