1. The problem statement, all variables and given/known data 2^n+6/5^4+n - 2 = 23 The equation is correct. You need to work the left side to come down to the 23 = 23 conclusion. What makes this task difficult for me is the fact that on the down side of the fraction, the number is 54+n which makes it impossible to work with the upper 2n+6 on the top of the fraction. By the way, the "- 2" is not on the down side of the fraction. 2. Relevant equations None. 3. The attempt at a solution 2^n+6/5^4+n - 2 = 23 = 2^n+4 * 2^2/5^4+n - 2 = 23 = (2/5)^n+4 * 4 - 2 = 23 Couldn't go any further.
