Question

I'm not sure what subject of math this would go in, but could someone explain how to simplify negative exponents please?

Answer 1

When you say "simplify negative exponents", what is it you're trying to do?
A negative exponent is just a positive exponent when put into the denominator.
\[e^{-1} == \frac{1}{e}\]
\[9^{-6} == \frac {1}{9^6}\]
etc. etc.
