Question

A matriz k= (aij)2×3,tal que aij =2.i+3j

Answer 1

Resposta:

$\left[\begin{array}{ccc}a11&a12&a13\\a21&a22&a23\end{array}\right]$

$\left[\begin{array}{ccc}5&8&11\\7&10&13\end{array}\right]$

Explicação passo a passo:

aij =2 . i + 3 . j

a11 = 2 . 1 + 3 . 1 = 2 + 3 = 5

a12 = 2 . 1 + 3 . 2 = 2 + 6 = 8

a13 = 2 . 1 + 3 . 3 = 2 + 9 = 11

a21 = 2 . 2 + 3 . 1 = 4 + 3 = 7

a22 = 2 . 2 + 3 . 2 = 4 + 6 = 10

a23 = 2 . 2 + 3 . 3 = 4 + 9 = 13
