\(\displaystyle a^{-x}=\frac{1}{a^x}\).

Example:

\(\displaystyle \frac{a^{-3}b^2}{c^{-4}}=\frac{b^2c^4}{a^3}\)

...if you want to have all positive exponents.

I'm not sure what the above means...?Mathgirl22 said:

If you are referring to the second of your four originally-posted exercises, and if you are asking if \(\displaystyle \frac{x}{y^3}\) is the correct simplification, then the answer would be "yes".

If you mean something else, please reply (in standard English) with clarification. Thank you!
