4 is cube root of 64 and since its -64 so its an imaginary number i never said its real

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.

@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\[\large (4i)(4i)(4i)=-64i\]
