5 - Escreva na forma de radical: a) 2^(1)/(5)= b) 4^(2)/(3)= c) x^(1)/(4)= d) 8^(1)/(2)= e) a^(5)/(7)= f) (a^3b)^(1)/(4)= g) (m^2n)^(1)/(5)= h) m^-(3)/(4)=

a) $2^{\frac {1}{5}} = \sqrt[5]{2}$<br />b) $4^{\frac {2}{3}} = \sqrt[3]{4^2} = \sqrt[3]{16}$<br />c) $x^{\frac {1}{4}} = \sqrt[4]{x}$<br />d) $8^{\frac {1}{2}} = \sqrt{8}$<br />e) $a^{\frac {5}{7}} = \sqrt[7]{a^5}$<br />f) $(a^{3}b)^{\frac {1}{4}} = \sqrt[4]{a^3b}$<br />g) $(m^{2}n)^{\frac {1}{5}} = \sqrt[5]{m^2n}$<br />h) $m^{-\frac {3}{4}} = \frac{1}{\sqrt[4]{m^3}}$
