Resposta:

$\left[\begin{array}{ccc}5&2\\2&1\\\end{array}\right] *\left[\begin{array}{ccc}2&3&3\\2&9&2\\\end{array}\right] =\left[\begin{array}{ccc}(5*2+2*2)&(5*3+2*9)&(5*3+2*2)\\(2*2+1*2)&(2*3+1*9)&(2*3+1*2)\end{array}\right]$

$=\left[\begin{array}{ccc}(10+4)&(15+18)&(15+4)\\(4+2)&(6+9)&(6+2)\end{array}\right]$

$=\left[\begin{array}{ccc}14&33&19\\6&15&8\end{array}\right]$
