Question
1. Determine whether (Q.), where a bab/2 for all a, b € Q is a group or not. a) show step for associative. b) show step for identity. c) show step inverse. 2. A permutation is an arrangement of objects in a definite order. The a and I are given as follows: a) Find ar. b) Find TT-¹. 3. A ring < R +, > are defined busing THREE (3) axioms that need to satisfy such as Abelian Group, Associative and Distributive Laws. Hence, show that <Z, +, > is a ring. 4. Explain the difference between Isomorphism and Homomorphism.
