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~~~~~~~~~~~~~~~.\\.

Tenha ótimos estudos mano ;D
