I don't understand how to grasp such a concept. Obviously the answer is in a+bi form, but I have no idea how to get there. ln(-.3675) ln(-13.4) Here are a few problems from my book, can anyone guide me through?

ln(-.3675) = ln(-13.4) = Do those answers look about right? Thanks!

For This is the same thing as ThePerfectHacker's formula. Remember that mine only works for real numbers. ln(-.3675) = ln(-13.4) = Yes, they're correct.
