Prove that (a-b) intersection (b-a) =null

Answer»

(a-B) MEANS that the set that contains elements in 'a' but not in 'b'


(b-a) means that the set that contains elements in 'b' but not in 'a'

so there is no common element in (a-b) and
(b-a)

so their intersection is a null set

(a-b) N (b-a) = null set
