Question

How do i simplify -3^-2 without a calculator?

Answer 1

Well, when you have a negative exponent, that means you can move it to the denominator and make it a positve exponent:

\[-(3)^{-2} = -\frac{ 1 }{ 3^{2} }\]

Also notice how I left that negative out. It needs to be out and not squared. So you should get it from there.
