    If this is a square 8^-2 then all you need to do is -8 x -8

    Yes @MadisonEmery a negative times a negative is a positive and 8 x 8 is 64

    This is not multiplication, this is an exponent. With negative exponents you put the 8^-2 under 1 like this: 1/8^-2 the answer is NOT 64 the answer is 1/64

    Im afraid Twistnflip is correct. 8^-2 = 1/ 8 * 8 = 1/8^2 = 1/64
