Question

como poderia resolver 16^3/4?

Answer 1

$\boxed{16^{ \frac{3}{4}} = \sqrt[4]{16^3} = \sqrt[4]{(2^4)^{3}} = \sqrt[4]{2^{12}} = 2^3 = 8}$

$\boxed{16^{- \frac{3}{4}} = \frac{1}{16^{ \frac{3}{4}}} = \frac{1}{ \sqrt[4]{16^3}} = \frac{1}{ \sqrt[4]{2^{12}}} = \frac{1}{2^3} = \frac{1}{8} = 0,125}$

Espero ter ajudado. :))
