In your case and , so your cube roots are , , and . Put back into rectangular form, they are , , and . Actually, you can just note that if is a root, then its conjugate must be, too. Generally suppose is a polynomial over a field with roots . The nth roots of unity are, by definition, the roots of the polynomial x − 1, and are thus algebraic numbers. As this polynomial is not irreducible (except for n = 1), the primitive nth roots of unity are roots of an irreducible polynomial (over the integers) of lower degree, called the nth cyclotomic polynomial, and often denoted Φn. The degree of Φn is given by Euler's totient function, which counts (among other things) the number of primitive nth roots of unity. The roots of Φn are exac… how to see word count in google docs
