 Wolfram Alpha says 5^(3i) = cos(3*ln(5))+i*sin(3*ln(5)), so it seems you still haven't figured out what complex numbers are or how they work.
 Not just Wolfram Alpha, any graphic calculator that is able to handle complex numbers.

 There is not a single online source that will confirm or support your claim that 5^(3i) = (-3,-123).

That's not quite what I said, the value x=5^(3i) is not a point, but a value.
x=-123
