Question

Escreva na representação de radical cada um dos números irracionais

Answer 1

a) $7^{0,333...}$ = $7^{1/3}$ = $\sqrt[3]{7}$

b) $2^{7/8}$ = $\sqrt[8]{2^7}$

c) $5^{3/4}$ = $\sqrt[4]{5^3}$

d) $9^{0,75}$ = $9^{3/4}$ = $\sqrt[4]{9^3}$

e) $(2/5)^{1/3}$ = $\sqrt[3]{2/5}$

f) $(4/9)^{1,666...}$ = $(4/9)^{5/3}$ = $\sqrt[3]{( \frac{4}{9})^5 }$

g) $(0,25)^{1,25}$ = $0,25^{5/4}$ = $\sqrt[4]{0,25^5}$

h) $(3,5)^{7/10}$ = $\sqrt[10]{3,7^7}$
