Question

Dadas as matrizes A = $\left[\begin{array}{cc}-1&3\\2&0\end{array}\right]$ , B =$\left[\begin{array}{cc}0&1\\1&0\end{array}\right]$ e C = $\left[\begin{array}{cc}3&1\\1&5\end{array}\right]$ , calcule $\left[\begin{array}{ccc}A+ (-B)\end{array}\right]$ + (-A) + C

Answer 1

Resposta:

Explicação passo-a-passo:

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