no, i wasn't saying you said anything. I was responding the the original question from the original poster where the person asked about a "real" root.

zepdrix · Answer

@itsmylife -4 should be the cube root of -64.$$\large (-4)(-4)(-4)=-64$$
I'm not sure why you're thinking it would be complex, did you confuse it with the square root? :o$$\large (4i)(4i)(4i)=-64i$$
