Talk:Principal root of unity

"In an integral domain, every primitive n-th root of unity is also a principal n-th root of unity"
Doesn't the non-example show that in an integral domain not "every primitive n-th root of unity is also a principal $$n$$-th root of unity" but only those roots whose values decremented by 1 are invertible (for the proof to hold)? --5.143.30.187 (talk) 07:31, 24 May 2022 (UTC)


 * I was wrong because of the definition of an integral domain. 5.143.30.187 (talk) 09:18, 24 May 2022 (UTC)
