let R be the relation defined on the set N of natural no.'s as, R={(x,y):x divides y:x,y belongs to N} then (3,9) belongs to R. WHY (9,3) AND (4,2) DOES NOT BELONG TO R?

Expert Answer:

The relation R is defined as:
R={(x,y):x divides y:x,y belongs to N}
 
Now, (3, 9) belongs to R as 3 divides 9.
 
But, (9, 3) does not belong to R as 9 does not divide 3.
Also, (4, 2) does not belong to R as 4 does not divide 2.
