You can't plot a function which yields imaginary numbers like your function 
(e.g. (-2)^(1/3) gives (-1)^(1/3)* 2^(1/3) which is approximately
	0.629961 + 1.09112 I)
with the simple Plot-Routine in Mathematica. You can either plot the real or
imaginary part or the absolute value with Plot, or you can try Plot3D.
