Note: There is a nasty typo on Exercise 2.57. It should read: Let n ∈ N+ and Ω the set of n-th roots of 1 [not -1.] (a) Verify that if n = 4 [not 2], then Ω = {1,i,-1,-i}, where i is the square root of -1. (b) Show that Ω is a group with n elements. (You may use, without proof, the facts that (i) Ω contains the roots of xn - 1 [not xn + 1], and (ii) there are exactly n such roots.) |
