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

Can you have negative exponents in the denominator?
You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
How will you simplify expressions with negative exponents to get positive exponents?
A negative exponent becomes positive in the reciprocal. So if you have a number a^x where x is negative, then, a^x = 1/(a^-x) and, since x is negative, -x is positive.
How do you change powers with negative exponents to powers with positive exponents?
by doing reciprocal
How do you figure out negative exponents?
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa
What do you get when you multiply a positive by a negative number?
When you multiply a positive number by a negative number you always get a negative number.
