WebIf ( a b) n = e then ( a b) n a = a. Since ( a b) n a = a ( b a) n, ( b a) n = e. This proves that the order of b a divides the order of a b. By symmetry, the order of a b divides the order … Web_____ (b) If AC = BC, then A = B. _____ (c) If AB = O, then either A = O or B = O. ______ (d) If A + C = B + C, then A = B. ____ (e) If A^2 = I, then A = plusminus I. _______ (f) If …

But, o ( a b) is not necessarily the order of a . b = H K. You may track which argument is not valid in your proof. The statement in the title is wrong. It should be If o ( a) = m, o ( b) = n and if a b = b a then o ( a b) divides l c m ( o ( a), o ( b)). Share Cite Follow answered Nov 24, 2015 at 8:20 scroll sticker
