Answer 1

Boa tarde!

Matriz:

$\begin{bmatrix}a11&a12&a13\\a21&a22&a23\\\end{bmatrix}$

_______________________________________________

$a11\Rightarrow\mathrm{2\times1+3\times1}\Rightarrow\mathrm{2+3}=\boxed{\boxed{5}}$

$a12\Rightarrow\mathrm{2\times1+3\times2}\Rightarrow\mathrm{2+6}=\boxed{\boxed{8}}$

$a13\Rightarrow\mathrm{2\times1+3\times3}\Rightarrow\mathrm{2+9}=\boxed{\boxed{11}}$

$a21\Rightarrow\mathrm{2\times2+3\times1}\Rightarrow\mathrm{4+3}=\boxed{\boxed{7}}$

$a22\Rightarrow\mathrm{2\times2+3\times2}\Rightarrow\mathrm{4+6}=\boxed{\boxed{10}}$

$a23\Rightarrow\mathrm{2\times2+3\times3}\Rightarrow\mathrm{4+9}=\boxed{\boxed{13}}$
