Question

Introduza no radical  os fatores externos :
0,3·∛5

Answer 1

$a*\sqrt[n]{b}=\sqrt[n]{a^{n}}*\sqrt[n]{b}$

Logo:

$\boxed{\boxed{a\sqrt[n]{b}=\sqrt{a^{n}*b}}}$
__________________________

$0,3=3/10$

$0,3\sqrt[3]{5}=(3/10)*\sqrt[3]{5}\\0,3\sqrt[3]{5}=\sqrt[3]{(3/10)^{3}*5}\\0,3\sqrt[3]{5}=\sqrt[3]{(3^{3}/10^{3})*5}\\0,3\sqrt[3]{5}=\sqrt[3]{(27/1000)*5}\\0,3\sqrt[3]{5}=\sqrt[3]{27/200}$
