Matriz:

$\begin{bmatrix}a11&a12\\a21&a22\\a31&a32\\\end{bmatrix}$

____________________________________________________

$\mathrm{a11}\Rightarrow\mathrm{3\times1+1}\Rightarrow\mathrm{3+1}=\boxed{\boxed{4}}$

$\mathrm{a12}\Rightarrow\mathrm{3\times1+2}\Rightarrow\mathrm{3+2}=\boxed{\boxed{5}}$

$\mathrm{a21}\Rightarrow\mathrm{3\times2+1}\Rightarrow\mathrm{6+1}=\boxed{\boxed{7}}$

$\mathrm{a22}\Rightarrow\mathrm{3\times2+2}\Rightarrow\mathrm{6+2}=\boxed{\boxed{8}}$

$\mathrm{a31}\Rightarrow\mathrm{3\times3+1}\Rightarrow\mathrm{9+1}=\boxed{\boxed{10}}$

$\mathrm{a32}\Rightarrow\mathrm{3\times3+2}\Rightarrow\mathrm{9+2}=\boxed{\boxed{11}}$
