Answer 1

Boa noite!

Temos uma Matriz Quadrada.


$\begin{bmatrix}a11&a12&a13\\a21&a22&a23\\a31&a32&a33\end{bmatrix}$

$\textup{a11}\rightarrow\textup{1+3}\ast1\rightarrow\textup{1+3}=\textup{4}$

$\textup{a12}\rightarrow\textup{1+3}\ast2\rightarrow\textup{1+6}=\textup{7}$

$\textup{a13}\rightarrow\textup{1+3}\ast3\rightarrow\textup{1+9}=\textup{10}$

$\textup{a21}\rightarrow\textup{2+3}\ast1\rightarrow\textup{2+3}=\textup{5}$

$\textup{a22}\rightarrow\textup{2+3}\ast2\rightarrow\textup{2+6}=\textup{8}$

$\textup{a23}\rightarrow\textup{2+3}\ast3\rightarrow\textup{2+9}=\textup{11}$

$\textup{a31}\rightarrow\textup{3+3}\ast1\rightarrow\textup{3+3}=\textup{6}$

$\textup{a32}\rightarrow\textup{3+3}\ast2\rightarrow\textup{3+6}=\textup{9}$

$\textup{a33}\rightarrow\textup{3+3}\ast3\rightarrow\textup{3+9}=\textup{12}$

$\begin{bmatrix}a11&a12&a13\\a21&a22&a23\\a31&a32&a33\end{bmatrix}$=$\begin{bmatrix}4&7&10\\5&8&11\\6&9&12\end{bmatrix}$
