For problem 9.3, how detailed should our explanation be? Is a mathematical proof required along with our reasoning in words? --Ysuo
Write out the real and imaginary parts for $ \log(a_1a_2) $ then choose the principal branch of log and add $ 2n\pi $ to get all the possible branch choices. Next do the same for $ \log(a_1)+\log(a_2) $ only using two different variables (one for each number) for the possible branches. Adding the results of the two logs together should give a relation between all the variables. Hope this helps --Rgilhamw 18:47, 4 October 2009 (UTC)
