Everything about Root of unity modulo n

In mathematics, a kth root of unity modulo n for positive integers k, n ≄ 2, is a root of unity in the ring of integers modulo n; that is, a solution x to the equation. If k is the smallest such exponent for x, then x is called a primitive kth root of unity modulo n. See modular arithmetic for notation and terminology. Wikipedia →
