Question

C = (a ij ) 3x3 tal que a ij = 2i – 4j +3

Answer 1

Resposta: $C = \left[\begin{array}{ccc}1&-3&-7\\3&-1&-5\\5&1&-3\end{array}\right]$

Explicação passo-a-passo:

Temos a matriz

$C = \left[\begin{array}{ccc}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{array}\right]$, onde $ij = 2i - 4j + 3$.

Logo:

$C = \left[\begin{array}{ccc}1&-3&-7\\3&-1&-5\\5&1&-3\end{array}\right]$
