What is the simplified form of \(\left(\frac{64x^{-6}}{27y^{9}}\right)^{-\frac{1}{3}}\)?
Answer and explanation
Correct answer: \(\frac{3x^{2}y^{3}}{4}\)
We get \(\left(\frac{64x^{-6}}{27y^{9}}\right)^{\frac{1}{3}}=\frac{4x^{-2}}{3y^{3}}\). The power \(-\frac{1}{3}\) gives the reciprocal \(\frac{3x^{2}y^{3}}{4}\).
