\(n=\sqrt{\frac{64}{729}}\) = \((\frac{64}{729})\)^(1/2)
\(\sqrt[3]{n} = \) = \(n^\frac{1}{3}\) = \(((\frac{64}{729})\)^(1/2))^1/3
= \((\frac{64}{729})\)^((1/2) * (1/3))= \((\frac{64}{729})\)^(1/6)
= \((\frac{2^6}{3^6})\)^(1/6) = \((\frac{2}{3})\)^(6*1/6)
= \(\frac{2}{3}\)
So, Answer is D
Hope it helps!

Since 8^2=64 & 27^2=729, n=8/27
Now, 2^3=8 & 3^3=27, which means cube root of n = 2/3
Answer is D
