Question

b) B(bij) 2x2, com bij = -3i + 2j por favorrrrr me ajudemm​

Answer 1

$b_{11}=-3.1+2.1=-3+2=-1\\b_{12}=-3.1+2.2=-3+4=1\\b_{21}=-3.2+2.1=-6+2=-4\\b_{22}=-3.2+2.2=-6+4=-2$

$\huge\mathtt{B=\begin{bmatrix}-1&1\\-4&-2\end{bmatrix}}$

Answer 2

Resposta:

Explicação passo-a-passo:

2 linhas e 2 colunas

B =

[b11 b12]

[b22 b22]

B(bij) 2x2, com bij = -3i + 2j

bij = - 3i + 2j

b11 = - 3.1 + 2.1 = -3+2= -1

b12 = - 3.1 + 2.2 = -3+4= 1

bij = - 3i + 2j

b21 = - 3.2 + 2.1 = - 6+2= - 4

b22 = - 3.2 + 2.2 = -6+4= -2

R :

[-1 1]

[-4 -2]
