\( \left(\frac{-8 w^{3}}{u}\right)^{2} \) Write your answer without parenthese \( \square \)

The expression simplifies to \( \frac{64 w^{6}}{u^{2}} \). This is because when you square a fraction, you square both the numerator and the denominator separately. \( (-8)^{2} \) gives you \( 64 \), and \( (w^{3})^{2} \) results in \( w^{6} \). Meanwhile, \( (u)^{2} \) gives you \( u^{2} \). So, all together, you have \( \frac{64 w^{6}}{u^{2}} \)!
