Your formatting is ambiguous. Do you mean everything after the carats to be in the powers?
Also, if you aren't familiar with exponents (which was what you've indicated in quite a few of your other posts), then it will be quite difficult for you to try to learn how to solve exponential equations. You might want to have a talk with your academic counsellor about course placement, since, according to your posts, you seem to be seriously lacking in background material.
Good luck!
