1. ## Solving x = log(x) type equations.

It looks like a simple problem, but for some reason, it's giving me trouble. How do you find the solution algebraically:

$x = 8\ log _2 x$

By drawing the 2 functions, I can see that there will be two solutions. But that's about all I can say right now. How do you find the values of these two roots?

2. ## Re: Logarithmic functions

You can not solve it elementary.
You could use numerical methods.
