    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

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

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