Is this ?

If so, you should note that complex exponentiation is best done using the exponential form of the complex number.

So

wow. never thought that it's that complicated. thank you !

the source where i got it from says that the answer is -0.42 - j0.66

also, my python calculator also says

>>> pow((3+4j),(1+2j))

(-0.41981317556195746-0.6604516942073323j)

how can we prove it ? - Dec 18th 2010, 04:47 AMProve It
Why don't you try evaluating the real and imaginary parts of the answer I've posted?
