f)³√1/27
g)5^√1/32
h)4^√256
i)5^√3125

Answer 1

a) $\sqrt[3]{-1000} = 10$

b) $-\sqrt{121} = -11$

c) $-\sqrt[3]{-64} = - (-4) = 4$

d) $\sqrt[3]{729} = 9$

e) $\sqrt[4]{81} = 3$

f) $\sqrt[3]{\frac{1}{27} } = \frac{1}{3}$

g) $\sqrt[5]{ \frac{1}{32}} = \frac{1}{2}$

h) $\sqrt[4]{256} = 4$

i) $\sqrt[5]{3125} = 5$
