Question

Simplifique os seguintes radicais:
a) √48=
b) ∛72=
c) ∛162=
d) ^4√208=

Answer 1

$a) \sqrt{48} = \sqrt{ 4^{2}*3 } =\boxed{4 \sqrt{3} } \\ \\ b) \sqrt[3]{72} = \sqrt[3]{ 2^{3}*3 } =\boxed{2 \sqrt[3]{3} } \\ \\ c) \sqrt[3]{162}= \sqrt[3]{ 3^{3}*3*2 }=\boxed{3 \sqrt[3]{6} } \\ \\ d)4 \sqrt{208} =4 \sqrt{4^{2}*13 } =\boxed{16 \sqrt{13} }$

Boa madrugada e bons estudos!
