Hi,
First you are probably working wit Phasors, so the Imaginary unit is missing
from your expression.
Second
A rather simple "function" would do
toPhasor[x_]:=Abs[x] Exp[I Arg[x]]
so
toPhasor[220 E^(I Pi/2)+220 E^(I 5 Pi/6)]
returns (in Input form)
220*Sqrt[3]*E^((2*I*Pi)/3)
and as we know 220 Sqrt[3] is approximately 380 (more precisely 381.05Volts)

I hope this helps
yehuda
