preciso de ajuda, pfvrr​

Answer 1

a)

$(– 1000)^{\frac{1}{3}} = (– 10^3)^{\frac{1}{3}}= – 10^{(3 × \frac{1}{3})} = – 10^{\frac{3}{3}} = – 10$

b)

$–\sqrt{121} = – 11$

c)

$– (– 64)^{\frac{1}{3}} = – (– 4^3)^{\frac{1}{3}}= – (– 4^{\frac{3}{3}}) = – (– 4) = 4$

d)

$81^{\frac{1}{4}} = (3^4)^{\frac{1}{4}} = 3^{\frac{4}{4}} = 3^1 = 3$

e)

$(\frac{1}{27})^{\frac{1}{3}}= ((\frac{1}{3})^3)^{\frac{1}{3}} = (\frac{1}{3})^{\frac{3}{3}}= (\frac{1}{3})^1 = \frac{1}{3}$

f)

$(\frac{1}{32})^{\frac{1}{5}}= ((\frac{1}{2})^5)^{\frac{1}{5}} = (\frac{1}{2})^{\frac{5}{5}} = (\frac{1}{2})^1 = \frac{1}{2}$
