Question

can some help me do this problem?

Answer 1

It depends whether or not you post it. :)

Answer 2

I'd argue that it's already in correct form but, anyways. Let me type up the solution.

Answer 3

\[\frac{c}{a+bi}\cdot\frac{a-bi}{a-bi}=\frac{ca-cbi}{a^2+b^2}\]

Answer 4

multipliy by conjugate the nominator and the denominator and you get 3+i

Answer 5

From what I've written, and reading what @myko has written, I think you can piece together what you're supposed to do. :)

Answer 7

Answer 8

Yup. :)
