Question

Dada as matrizes A = (2 3 -1 2) e B = (-1 2 0 0) calcule:

Answer 1

Resposta:

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

$b)\left[\begin{array}{ccc}2&3\\-1&2\\\end{array}\right] + \left[\begin{array}{ccc}-(-1)&-(2)\\-0&-0\\\end{array}\right] = \left[\begin{array}{ccc}2+1&3-2\\-1-0&2-0\\\end{array}\right]\\\\ \left[\begin{array}{ccc}3&1\\-1&2\\\end{array}\right]$
