Question

Efetue as operações indicadas nos radicandos e, em seguida, calcule as raizes b) ³√16.4

Answer 1

$\mathsf{\sqrt[3]{16\times4}}$

$\mathsf{\sqrt[3]{64}}$

Fatorando:

$\begin{array}{c|l}64&2\\32&2\\16&2\\8&2\\4&2\\2&2\\1&\bold{64=2^6}\end{array}$

$\mathsf{\sqrt[3]{2^6}}$

$\mathsf{2^{\tfrac{6}{3}}}$

$\boxed{\boxed{\mathsf{2^3 = 8}}}$
