Some calculators say (-2)2/3 is equal to ##-\frac{1}{2^\frac{1}{3}}+i\frac{3^\frac{1}{2}}{2^\frac{1}{3}}## while others say its equal to ##4^{\frac{1}{3}}## i.e. ##|-\frac{1}{2^\frac{1}{3}}+i\frac{3^\frac{1}{2}}{2^\frac{1}{3}}|##.
I think I am right to imply from above that (-2)2/3 does have an imaginary component. But if it is so, then why do many calculus books, while speaking about cusps, treat x2/3 as a real-valued function by plotting it in the negative x region of the real plane?
What did I miss?
