urgente porfavor gracis

Answer 1

$\sqrt[3]{16}- \sqrt[3]{54}\qquad 16=2^4\quad 54= 2*3^3 \\ \\ \sqrt[3]{2^4}- \sqrt[3]{2*3^3}= \\ \\ \sqrt[3]{2^3} \sqrt[3]{2} - \sqrt[3]{2} \sqrt[3]{3^3} = \\ \\ 2 \sqrt[3]{2} -3 \sqrt[3]{2}= (2-3) \sqrt[3]{2}= \boxed{- \sqrt[3]{2} }$

Espero que te sirva, salu2!!!!
