Question

construa a matriz B=3x3 tal que Bij=5j

Answer 1

Resposta:

$| 5 \: \: 10 \: \: 15| \\| 5 \: \: 10 \: \: 15| \\| 5 \: \: 10 \: \: 15|$

Explicação passo-a-passo:

$| b11 \: \: b12 \: \: b13| \\|b21 \: \: b22 \: \: b23| \\|b31 \: \: b32 \: \: b33|$

$b11 = 5j = 5 \times 1 = 5$

$b12 = 5j = 5 \times 2 = 10$

$b13 = 5j = 5 \times 3 = 15$

$b21 = 5j = 5 \times 1 = 5$

$b22 = 5j = 5 \times 2 = 10$

$b23 = 5j = 5 \times 3 = 15$

$b31 = 5j = 5 \times 1 = 5$

$b32 = 5j = 5 \times 2 = 10$

$b33 = 5j = 5 \times 3 = 15$
