Step 1The rule for raising a power to a power is that you multiply the exponents. Combining that with the Distributive Property yeilds the following:  (  A      B    M        )    N    =      A    N        B          M      N      In this case,   A  =  2  ,     B  =  b  ,     M  =  4  ,     N  =  −  1Also, the rule for negative expontents is that they go in the denominator as follows:      A          −      M        =      1          A      M      Use these two formulas to get to your answer.
