Question

obter a matriz B=(bij)2x2 definida por bij+j-1

Answer 1

Olá, Talinekollas!

$B = \left[\begin{array}{ccc}b11&b12\\b21&b22\end{array}\right]$

Fórmula geral: $bij = j - 1$

Calculando os termos:

$b_{11} = 1 - 1 = 0$
$b_{12} = 2 - 1 = 1$
$b_{21} = 1 - 1 = 0$
$b_{22} = 2 - 1 = 0$

Jogando na matriz:

$\boxed{\boxed{B = \left[\begin{array}{ccc}0&1\\0&0\end{array}\right]}}$
