Sorry i can tell im being stupid and missing something here. 1. The problem statement, all variables and given/known data if 7^(3+2i)=re^(i[theta]) find values of the real numbers r and [theta] 2. Relevant equations er^(i[theta])=r(cos[theta]+isin[theta]) 3. The attempt at a solution Ok you know that 7^(3+2i)=(7^3)(7^2i) but i dont know what to do from here. I think there must be a simple formula or concept i am missing :s. There are similar questions aswel such as (1+i)^i which i also dont know how to solve. I know it must involve getting the i off the top but am unsure how to go about this. Advice would be appreciated, Thanks!
