Question

ola pessoal me ajudem por favor!!! Des de jah agradeço...

Determine X e Y na igualdade das matrizes:
$A= \left[\begin{array}{ccc}2&3\\log_{2}64 &x ^{3} \\\end{array}\right] e B= \left[\begin{array}{ccc}2&3\\y&125\\\end{array}\right]$

Answer 1

$x^3=125\\\\ x =\sqrt[3]{125}\\\\ x=\sqrt[3]{5^3}\\\\ \boxed{x=5}$

$log_2\ 64=y\\\\ 2^y=64\\\\ 2^y=2^6\\\\ \boxed{y=6}$
