(1 3 2 )
 2 6 4
 1 2 2


o elemento M23 é:

Answer 1

E aí brother,

a matriz genérica de M é dada por:

$M= \left|\begin{array}{ccc}m_{11}&m_{12}&m_{13}\\m_{21}&m_{22}&\boxed{m_{23}}\\m_{31}&m_{32}&m_{33}\end{array}\right| ~~\Longrightarrow~~ M = \left|\begin{array}{ccc}1&3&2\\2&6&\boxed{4}\\1&2&2\end{array}\right|\\\\\\ O~elemento~M_{23}=4~~~~~~~~~~~~~~~.\\.$
