0 -2 1]

b=[ 1 0 3
-1 3 5
2 -5 3 ]


calcule C - A + B=​

Answer 1

Explicação passo-a-passo:

C - A + B

$\left[\begin{array}{ccc}0&4&-6\\-3&0&4\\-1&-6&3\end{array}\right]-\left[\begin{array}{ccc}3&5&7\\9&-1&2\\0&-2&1\end{array}\right]+\left[\begin{array}{ccc}1&0&3\\-1&3&5\\2&-5&3\end{array}\right]$

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

$\left[\begin{array}{ccc}-3&-1&-13\\-12&1&2\\-1&-4&2\end{array}\right]+\left[\begin{array}{ccc}1&0&3\\-1&3&5\\2&-5&3\end{array}\right]$

$\left[\begin{array}{ccc}-3+1&-1+0&-13+3\\-12+(-1)&1+3&2+5\\-1+2&-4+(-5)&2+3\end{array}\right]=\left[\begin{array}{ccc}-2&-1&-10\\-13&4&7\\1&-9&5\end{array}\right]$
