use the rules for multiplying integers.
Pos times pos equals pos
neg times neg equals posneg times pos or pos times neg equals neg
and keep in mind that a negative exponent turns positive by using the recipricol (changing it to a fraction)
(8 2)-2 = 82*-2 = 8-4 = 1/84 = 1/8*8*8*8 = 1/4096
(8 2)-2 = (8 . 8) -2 = 64-2 = 1/642 = 1/64*64 = 1/4096
Hope this answers your question
