Simplify (x^-4 / y^-10)^(5/4)

Simplify: \(\left(\frac{x^{-4}}{y^{-10}}\right)^{5/4}\)

Solution

\[ \left(\frac{x^{-4}}{y^{-10}}\right)^{5/4} \]

\[ = (x^{-4} \cdot y^{10})^{5/4} \]

\[ = x^{-4 \cdot \frac{5}{4}} \cdot y^{10 \cdot \frac{5}{4}} \]

\[ = x^{-5} \cdot y^{25/2} \]

\[ = \frac{y^{25/2}}{x^5} \]

Final Answer:

\[ \boxed{\frac{y^{25/2}}{x^5}} \]
