Here's the Solution to this Question

Let R be the relation on the set A= \{1,2,3,4,5,6,7\} defined by the rule (a,b)\in R if the integer product ab is divisible by 4.

Let us list the elements of R:

R=\{(1,4),(4,1), (2,4),(4,2),(2,6),(6,2), (3,4), (4,3), (4,4),

(4,5),(5,4),(4,6),(6,4),(4,7),(7,4)\}


Let us list the elements of R^{-1}:

R^{-1}=\{(a,b):(b,a)\in R\}=\{(4,1),(1,4),(4,2),(2,4),(6,2),(2,6), (4,3),

(3,4), (4,4), (5,4),(4,5),(6,4),(4,6),(7,4),(4,7)\}=R.
