Answer 2

Resposta:

$a)\\\\\begin{pmatrix}5&1\\ \:3&0\end{pmatrix}+\begin{pmatrix}-2&6\\ \:1&-8\end{pmatrix}\\\\\\=\begin{pmatrix}5+\left(-2\right)&1+6\\ 3+1&0+\left(-8\right)\end{pmatrix}\\\\\\=\begin{pmatrix}3&7\\ 4&-8\end{pmatrix}\\\\\\b)\\\\\begin{pmatrix}10&18\\ \:\:\:-9&15\end{pmatrix}+\begin{pmatrix}-7&0\\ \:\:\:12&-14\end{pmatrix}\\\\\\=\begin{pmatrix}10+\left(-7\right)&18+0\\ \left(-9\right)+12&15+\left(-14\right)\end{pmatrix}\\\\\\=\begin{pmatrix}3&18\\ 3&1\end{pmatrix}$

$c)\\\\\begin{pmatrix}3&5&-8\\ \:0&-6&1\\ \:1&0&-2\end{pmatrix}+\begin{pmatrix}1&-5&-1\\ \:-6&0&10\\ \:3&2&1\end{pmatrix}\\\\\\=\begin{pmatrix}3+1&5+\left(-5\right)&\left(-8\right)+\left(-1\right)\\ 0+\left(-6\right)&\left(-6\right)+0&1+10\\ 1+3&0+2&\left(-2\right)+1\end{pmatrix}\\\\\\=\begin{pmatrix}4&0&-9\\ -6&-6&11\\ 4&2&-1\end{pmatrix}\\\\d)\\\\\begin{pmatrix}5&-2\\ \:-3&1\end{pmatrix}+\begin{pmatrix}0&-2\\ \:9&3\end{pmatrix}-\begin{pmatrix}-4&10\\ \:-1&7\end{pmatrix}$

$=\begin{pmatrix}5+0&\left(-2\right)+\left(-2\right)\\ \left(-3\right)+9&1+3\end{pmatrix}-\begin{pmatrix}-4&10\\ -1&7\end{pmatrix}\\\\\\=\begin{pmatrix}5&-4\\ 6&4\end{pmatrix}-\begin{pmatrix}-4&10\\ -1&7\end{pmatrix}\\\\\\=\begin{pmatrix}5-\left(-4\right)&\left(-4\right)-10\\ 6-\left(-1\right)&4-7\end{pmatrix}\\\\\\=\begin{pmatrix}9&-14\\ 7&-3\end{pmatrix}$
