anonymous · Answer

shortly when you see power outside of the parenthesis multiply it with the power of the num inside of the parenthesis 
and when same kind of numbers need to be multiply just add the power of the same kind when dividing same numbers just subtract their powers

$$\left(\frac{4y^2}{x^4}\right)^3 = \frac{64y^6}{x^{12}}$$

$$\frac{x^5}{y^4}  \frac{64y^6}{x^{12}} = \frac{x^564y^6}{y^4x^{12}}$$

Simplifying you get the correct answer...
