I would use (Euler and de Moivre) $$ z^n=r^n(\cos \varphi+i\sin \varphi)^n=r^n(\cos n\varphi + i\sin n\varphi) $$ which gives you the...

I don't know how much complex analysis you have had. If you just want to multiply by something to make the denominator real, notice...

Agree.
You may get better/more answers if you formulate a more specific question rather than just this "check my work" format with three pages... -
TensorCalculus posted the thread Making the denominator of a certain fraction real in Precalculus Mathematics Homework Help.Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,##...
