In set A, x belongs to RAlso in set B, x belongs to RSo iwe can say (x=x) its possibleIf there is no element common in set A,B then their intersection will be phiBut ifY of set A=Y of set B their is something commonBy taking y=y i.e. e^x=e(-x)We can say it is possible when x=0So thier is something vommon and intersection is not null
