1. The problem statement, all variables and given/known data 4^(x+2)=9 2. Relevant equations basically all I want to know is what is the best way to go about solving a problem like this. 3. The attempt at a solution I know how to convert a problem as such 4^(3x)=10 using. [log(<base>4,10)]/3 = X. however I need some help with addition and subtraction in exponents with one base equaling another number with a different base.
