Question

Pra hoje gentee, alguém me ajudaaaaa

Answer 1

$\left[\begin{array}{ccc} x^{2} &1\\y& z^{2} \\\end{array}\right] - \left[\begin{array}{ccc}2&-3\\-5&-1&\end{array}\right] = \left[\begin{array}{ccc}-1&4&\8&8&10\8&\end{array}\right]$

$\left[\begin{array}{ccc} x^{2} -2&4\\y+5& z^{2}+1 \\\end{array}\right] = \left[\begin{array}{ccc}-1&4\\8&10\end{array}\right]$

$x^{2} -2=-1$
$x^{2} =1$
$x= \sqrt{1}$
$x=+ou-1$

$y+5=8$
$y=3$

$z^{2} +1=10$
$z^{2} =9$
$z= \sqrt{9}$
$z=3$
