**drwls**, Wednesday, March 12, 2008 at 1:31pm4^(n+1) = 2^[2*(n+1)]= 2^(2n+2)

8^(n-2)= (2^3)^(n-2) = 2^(3n-6)

If the 8^(n-2) is supposed to be in a denominator,

2^n * 4^(n+1)

____________

8^(n-2)

= 2^(n + 2n + 2 -3n +6)

= 2^8 = 256

no matter what n is. Pick a value of n and prove it for yourself.
