SUMMARY

The equation R = ((a^-x)-(b^-x))/((c^-x)-(a^-x)) can be solved for x by first rewriting it as R = (1/a^x - 1/b^x)/(1/c^x - 1/a^x). To simplify the equation, combine the terms in both the numerator and the denominator. This approach allows for a clearer path to isolate x in terms of R and the constants a, b, and c.

Your equation can be rewritten as
[tex]R = \frac{1/a^x - 1/b^x}{1/c^x - 1/a^x}[/tex]

I would start with combining the two expressions in the numerator and the two in the denominator and simplify, then see where that takes me.
