There are only two complex arithmetic problems on this set, since you have seen complex numbers before. This one is a little involved, however. You may want to make judicious use of; calculator or a symbol manipulation language like Maple. Of course there is a reason for the fancy real.
This is extremely frustrating because im sure im doing the right process but not getting the correct answer.
