-
A.
(frac{r}{2}) -
B.
2r -
C.
(frac{1}{2r}) -
D.
(frac{2}{r})
Correct Answer: Option B
Explanation
(sqrt[3]{(64r^6)^{frac{1}{2}}})
= (sqrt[3]{((8r^{3})^{2})^{frac{1}{2}}})
=(2r)
Simplify (sqrt[3]{(64r^{-6})^{frac{1}{2}}})
(sqrt[3]{(64r^6)^{frac{1}{2}}})
= (sqrt[3]{((8r^{3})^{2})^{frac{1}{2}}})
=(2r)
