The cube route negative 27
The cube route negative 27= -27^1/3= -3, some people will quibble with this. OR,
(-27)^1/3=3(-1)^(1/3)-This is the "complex" root.
\(\sqrt[3]{-27}=-3\)
because -3*-3*-3 = -27
There are 2 other complex roots as well but you probably do not need to worry about those.
Those would be \(3e^{\frac{\pm\pi i}{3}}\)
