Question

R on a set A A relation R on the set A={a,b,c,d,e) is defined as follows: R={(a,a),(a,b),(b,a),(b,b), (c,c),(c,d),(c,e), (d,c),(d,d), (d,e),(e,c), (e,d),(e,e)}. Determine the equivalence classes of R n​

Answer 1

Answer:

equalence classes of R ={(a,b),(b,a),(c,d),(d,c),(c,e),(e,c)} n(R)=6
