Alguem sabe essa a resposta dessa Matriz?

Answer 1

Resolução:
C = (A + B)²

$\left[\begin{array}{cc}1&-1\\2&3\\\end{array}\right] + \left[\begin{array}{ccc}0&1\\3&8\\\end{array}\right] =$

$\left[\begin{array}{ccc}1+0&-1+1\\2+3&3+8\\\end{array}\right] = \left[\begin{array}{ccc}1&0\\5&11\\\end{array}\right]$

$\left[\begin{array}{ccc}1&0\\5&11\\\end{array}\right] . \left[\begin{array}{ccc}1&0\\5&11\\\end{array}\right] =$

$\left[\begin{array}{ccc}1.1+0.5&1.0+0.11\\5.1+11.5&5.0+11.11\\\end{array}\right] = \left[\begin{array}{ccc}1&0\\60&121\\\end{array}\right]$
