1. ## exponents

(-4)^2 gives me 16

4^2 = 1/16

Why is (-4)^(-2)= -1/16

why is it not 1/((-4)(-4)) to get a 1/16

I have it I think that I typed it into my calculator incorrectly to check my solution. Thanks

3. As you can see here, (-4)^(-2) is indeed 1/16.

On the other had, -4^(-2) is interpreted as $\displaystyle -\frac{1}{4^2}$, which is -1/16.
