Answer:
Step-by-step explanation:
(i) A ∪ ( A ∩ B ) = A
L.H.S. = A ∪ (A ∩ B)
= (A ∪ A) ∩ (A ∪ B) ( वितरण गुण )
= A ∩ (A ∪ B) [ ∵ A ∪ A = A ]
= A [ ∵ A ⊂ A ∪ B ]
= R.H.S.
L.H.S. = R.H.S.
∴ A ∪ ( A ∩ B ) = A
(ii) A ∩ ( A ∪ B ) = A
L.H.S. = A ∩ ( A ∪ B )
= (A ∩ A) ∪ (A ∩ B) ( वितरण गुण )
= A ∪ ( A ∩ B ) [ ∵ A ∩ A = A ]
= A [ ∵ A ∩ B ⊂ A ]
= R.H.S.
L.H.S. = R.H.S.
अतः A ∩ ( A ∪ B ) = A
