Boa tarde!
Obteremos a seguinte matriz:
![\left[\begin{matrix}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{matrix}\right]\\=\left[\begin{matrix}5(1)-3(1)&5(1)-3(2)&5(1)-3(3)\\5(2)-3(1)&5(2)-3(2)&5(2)-3(3)\\5(3)-3(1)&5(3)-3(2)&5(3)-3(3)\end{matrix}\right]\\\boxed{=\left[\begin{matrix}2&-1&-4\\7&4&1\\12&9&6\end{matrix}\right]}](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Bmatrix%7Da_%7B11%7D%26amp%3Ba_%7B12%7D%26amp%3Ba_%7B13%7D%5C%5Ca_%7B21%7D%26amp%3Ba_%7B22%7D%26amp%3Ba_%7B23%7D%5C%5Ca_%7B31%7D%26amp%3Ba_%7B32%7D%26amp%3Ba_%7B33%7D%5Cend%7Bmatrix%7D%5Cright%5D%5C%5C%3D%5Cleft%5B%5Cbegin%7Bmatrix%7D5%281%29-3%281%29%26amp%3B5%281%29-3%282%29%26amp%3B5%281%29-3%283%29%5C%5C5%282%29-3%281%29%26amp%3B5%282%29-3%282%29%26amp%3B5%282%29-3%283%29%5C%5C5%283%29-3%281%29%26amp%3B5%283%29-3%282%29%26amp%3B5%283%29-3%283%29%5Cend%7Bmatrix%7D%5Cright%5D%5C%5C%5Cboxed%7B%3D%5Cleft%5B%5Cbegin%7Bmatrix%7D2%26amp%3B-1%26amp%3B-4%5C%5C7%26amp%3B4%26amp%3B1%5C%5C12%26amp%3B9%26amp%3B6%5Cend%7Bmatrix%7D%5Cright%5D%7D "\left[\begin{matrix}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{matrix}\right]\\=\left[\begin{matrix}5(1)-3(1)&5(1)-3(2)&5(1)-3(3)\\5(2)-3(1)&5(2)-3(2)&5(2)-3(3)\\5(3)-3(1)&5(3)-3(2)&5(3)-3(3)\end{matrix}\right]\\\boxed{=\left[\begin{matrix}2&-1&-4\\7&4&1\\12&9&6\end{matrix}\right]}")
