Question

Escreva a matriz quadrada A do tipo 2x2, tal que aij =isso ao quadrado +j.

Answer 1

$A=\begin{vmatrix}a_{11}&a_{12}\\a_{21}&a_{22}\end{vmatrix}$

$\mathsf{a_{11}=1^2+1=1+1=2}\\\mathsf{a_{12}=1^2+2=1+2=3}\\\mathsf{a_{21}=2^2+1=4+1=5}\\\mathsf{a_{22}=2^2+2=4+2=6}$

$A=\begin{vmatrix} 2&3\\5&6\end{vmatrix}$
