Generalizations of de Moivre's theorem can be used to write explicit expressions for which numbers?
AThe nth roots of unity
BThe prime factors of n
CThe zeros of sin x
DRoots of real quadratics
Answer & Solution
Correct answer: A. The nth roots of unity
Extending the theorem to fractional exponents gives all complex z with z^n = 1, the nth roots of unity.
