1. The problem statement, all variables and given/known data To solve the following equation for x in terms of R and 3 constants a,b, and c: R = ((a^-x)-(b^-x))/((c^-x)-(a^-x)) 2. Relevant equations Just the given equation 3. The attempt at a solution I have tried taking the natural log of both sides but that doesn't seem to get me anywhere. Any suggestions?
