Resposta:

Explicação passo-a-passo:

B= (bij) 2×3 tal que bij= (3i - j)

2 linhas e 3 colunas

b11 b12 b13

b21 b22 b23

bij= (3i - j)

b11 = 3.1 - 1 = 3 - 1 = 2

b12 = 3.1 - 2 = 3 - 2 = 1

b13 = 3.1 - 3 = 3 - 3 = 0

bij= (3i - j)

b21 = 3.2-1= 6-1= 5

b22 = 3.2-2 = 6-2 = 4

b23 = 3.2-3 = 6-3 = 3

B =

[2 1 0]

[5 4 3]

R.:

B =

[2 1 0]

[5 4 3]
