[6 10 8 7]
[1 2 -5 -1] dê o valor de
a)a34 b)a22 c)a13 d)a31+a24​

Answer 1

Explicação passo-a-passo:

$\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } \: \: \mathsf {OI, TUDO \: \: J\acute{O}IA \: ? \: \:\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } }$

$\left[\begin{array}{ccc} \sf{ a_{11}}& \sf{ a_{12} }&\sf{ a_{13} }&\sf{ a_{14} }\\\sf{ a_{21} }&\sf{ a_{22} }&\sf{ a_{23} }&\sf{ a_{24} }\\\sf{ a_{31} }&\sf{ a_{32} }&\sf{ a_{33} }&\sf{ a_{34} }\end{array}\right]$

a)

$\sf{ a_{34} = \boxed{\red{ \sf{ - 1}}}}$

b)

$\sf{ a_{22} = \boxed{\red{ \sf{10}}}}$

c)

$\sf{ a_{13} = \boxed{\red{ \sf{0}}} }$

d)

$\sf{ a_{31} + \sf{ a_{24} }\rightarrow1 + 7 = \boxed{\red{ \sf{8}}}}$
