Answer 1

Use this property:
\[\frac{1}{a ^{-n}}=a^n\]

Answer 2

Or to put it in words you could say...if a factor has a negative exponent and is in the denominator, take it to the numerator and make the exponent positive.

Answer 3

You need to replace both n's with the 5

Answer 4

\[\frac{1}{a ^{-5}}=a^5\]

Answer 5

Yes. That's it. So now your answer is:
\[8a^5b\]
