Question

me ajudem com essa matriz

Answer 1

Resposta:

60

Explicação passo-a-passo:

$b_{11} =1^{2} +1 = 2$

$b_{12} =1^{2} +2 = 3$

$b_{13} =1^{2} +3 = 4$

$b_{21} =2^{2} +1 = 5$

$b_{22} =2^{2} +2 = 6$

$b_{23} =2^{2} +3 = 7$

$b_{31} =3^{2} +1 = 10$

$b_{32} =3^{2} +2 = 11$

$b_{33} =3^{2} +3 = 12$

$B=\left[\begin{array}{ccc}2&3&4\\5&6&7\\10&11&12\end{array}\right]$

$2+3+4+5+6+7+10+11+12=60$
