Solving $\ln$ divided by $\ln$.

Question

I am having trouble figuring out how to calculate this. Thank you for your help.

$$0.926 = \frac{\ln(1+0.8u)}{\ln(1+u)}$$

What does $u$ equal?

Answer 1

If you use a method to approximate the value of u or WolframAlpha, you should get: 15.68427584

There doesn't seem to be a method to find an exact answer.
