fake proofs - imaginary number i equals 6/3.4641?

43=64
so the third root of 64 should be 4 than.
364=4
But if you calculate the third root of -64
with WolframAlpha( http://www.wolframalpha.com/input/?i=third+root+of+-64 )
you get a complex number with an imaginary part of 3.4641016151i and a real part of 2




so if the third root of 464 equals 4 AND 2+3.46410162i (which i know is a bit foolish) than you could actually reform it like this
3642+3.46410162i|2
364263.46410162i|/3.46410162
36423.4641016263.46410162i



and this have to be totally wrong, so my question is, where exactly is the mistake?
