On z define * by a*b a
WebAnswer. The element in the brackets, [ ] is called the representative of the equivalence class. An equivalence class can be represented by any element in that equivalence class. So, in Example 6.3.2 , [S2] = [S3] = [S1] = {S1, S2, S3}. This equality of equivalence classes will be formalized in Lemma 6.3.1. Web(d) On Z, define * by letting a∗b = c, where c is the smallest integer greater than both a and b. (e) On Z+, define * by letting a∗b = c, where c is the largest integer less than the product of a and b. (f) Let H and K be the subsets of M 2(R) consisting of all matrices of the form; H = {[ a b −b a] for a,b ∈ R}. K = {[ a 0 b c] for a,b,c ∈ R}.
