Webnth root of unity, then 1 != !1 = !. Hence 1 is the identity for this set. Suppose e2ˇi n k is any nth root of unity, then e 2ˇi n (n k) is an nth root of unity. Note that e2ˇi n ke 2ˇi n (n k) = e2ˇi = 1. Therefore every nth root of unity has a multiplicative inverse that is also an n throot of unity, and so the n roots of unity form a ...
