Question

determine a matriz Aij (2×3) = 5i-2j ? ​

Answer 1

Resposta:

Aij (2×3) = 5i - 2j

a₁₁ = 5.1 - 2.1 = 3

a₁₂ = 5.1 - 2.2 = 1

a₁₃ = 5.1 - 2.3 = - 1

a₂₁ = 5.2 - 2.1 = 8

a₂₂ = 5.2 - 2.2 = 6

a₂₃ = 5.2 - 2.3 = 4

$\left[\begin{array}{ccc}3&1&-1\\8&6&4\\\end{array}\right]_{2x3}$

bons estudos!
