Question

ME AJUDEMMM!!!!!! Dadas as matrizes calcule:

Answer 1

A) $A+B=$ $\left[\begin{array}{ccc}1&-3&5\\0&2&-4\end{array}\right] + \left[\begin{array}{ccc}3&1&-8\\5&1&0\end{array}\right] =\left[\begin{array}{ccc}4&-2&-3\\5&3&-4\end{array}\right]$

B)$A-B=$ $\left[\begin{array}{ccc}1&-3&5\\0&2&-4\end{array}\right] - \left[\begin{array}{ccc}3&1&-8\\5&1&0\end{array}\right] =\left[\begin{array}{ccc}-2&-4&13\\-5&1&-4\end{array}\right]$

C) $2A+C^t=$ $\left[\begin{array}{ccc}2(1)&2(-3)&2(5)\\2(0)&2(2)&2(-4)\end{array}\right] + \left[\begin{array}{ccc}2&9&-3\\6&0&-1\end{array}\right] = \left[\begin{array}{ccc}4&3&7\\6&4&-9\end{array}\right]$

D) $3A+2B-C^t=\left[\begin{array}{ccc}3&-9&15\\0&6&-12\end{array}\right]+ \left[\begin{array}{ccc}6&2&-16\\10&2&0\end{array}\right]-\left[\begin{array}{ccc}2&9&-3\\6&0&-1\end{array}\right]=$

$\left[\begin{array}{ccc}9&-7&-1\\10&8&-12\end{array}\right]-\left[\begin{array}{ccc}2&9&-3\\6&0&-1\end{array}\right]=\left[\begin{array}{ccc}7&-16&2\\4&8&-11\end{array}\right]$

E) $(A+B)^t+C=\left[\begin{array}{ccc}4&5\\-2&3\\-3&-4\end{array}\right]+\left[\begin{array}{ccc}2&6\\9&0\\-3&-1\end{array}\right]=\left[\begin{array}{ccc}6&11\\7&3\\-6&-5\end{array}\right]$

Espero ter ajudado. Editar em LaTeX deu um trabalho, então demorou um pouco.

Qualquer coisa, fala aí!
