1. For the set X={m,n,p,q,r,s}, let R be relation on P(X), the power set of X, given by A R B if A and B have the same number of elments.
a) Mention all the elments in {{m}]
b) Describe threee elememnts in {{p.q}]
2. Let C={i,-1,-i,1} where i^2 =-1. The realtion R on C given by x R y iff xy=plus or minus 1 in an equvalance relation on C. Give the partition of C associated with R.
