Log base 2
Does the log contain the sum of both combinations? (Then you should have added more brackets)

Sorry I formulated the inequality wrong. It's fixed now.

The log only contains the binomial.

I think it might be easier just to do this numerically...

You can try to do:

2^LH = 2^RH

But I think the best approach is a numerical method.
