Relation "r" is these pairs (5,3), (7,5).



Relation "s" is these pairs (2,3), (2,5), (2,7), (3,5), (3,7), (5,7).



The post does not define and does not explain what is "rs".



But based on what I said before, you, PROBABLY, may complete this assignment on your own.



If it is the intersection of the sets  "r"  and  "s", then rs is the EMPTY set.
