. In parts (a) and (b) below, a group [0; 1:] is given as well as two elements :13, y of G. Compute the following for each group: (i) 33 * :9 (ii) :63 (iii) The cyclic group generated by :13. (iv) The order of :8. (V) 9'4 The two groups: Use the standard binary operation for a: in each part. (a) G=Z15 (b) G=R*XZB Elements: 2: = 9 and y = 13 Elements: :1: = (1, 6) and y = (3, 5)
