    1^(1/3) a complex number?

    I simply don't understand what this question is asking! (A common problem in mathematics, I assume.) This is the question:

    "Determine the indicated roots of the given complex number."
    Question seven says: "1^(1/3)"

    So... determine the third roots of... one? But one isn't a complex number! What's going on here?

    Here are three cube roots of 1:
    {\zeta _k  = e^{\displaystyle{\frac{{2k\pi i}}{3}}} ,\;\;k =  - 1,0,1}
