Hi,

I've been having problems solving equations where the variable I'm interested in appears inside and outside of powers. I'm not sure how to isolate the variable I want to find.

I'm starting to think that there's no closed form solution to this and I may have to solve by other means. The question I'm trying to solve is as follows:

Re-arranging to find theta as a function of the other variables.

Any help would be much appreciated!
