Simplify with Positive Exponents:
(2x^{-2}b^{4})^{-2}
I know the correct answer is
but for some reason I keep getting a totally different answer. Which is:
I am following the rules of the exponents but maybe I am making a simple mistake somewhere? Can someone explain to me how to get the correct answer? Thank you!
Edit: I figured out what I was doing wrong!
(2x^{-2}b^{4})^{-2 }-4x^{4}b^{-8}
I didn't distributed the -2 properly.
