Q. If A={1,2,3,4},B={3,4,5,6},U={1,2,3,4,5,6} then prove De Morgan's law. De Morgan's law: first Law: (A∪B)′=A′∩B′ Second Law: (A∩B)′=A′∪B′
Find Union of A and B: First, let's find the union of A and B. A∪B={1,2,3,4}∪{3,4,5,6}={1,2,3,4,5,6}
Find Complement of Union in U: Now, let's find the complement of A∪B in U.(A∪B)′=U−(A∪B)={1,2,3,4,5,6}−{1,2,3,4,5,6}={}
Find Complements of A and B: Next, find the complements of A and B in U separately. A′=U−A={1,2,3,4,5,6}−{1,2,3,4}={5,6}B′=U−B={1,2,3,4,5,6}−{3,4,5,6}={1,2}
Find Intersection of Complements: Now, let's find the intersection of A′ and B′.A′∩B′={5,6}∩{1,2}={}
