Question

7. For any sets A and B, prove that:
(i) (A-B) N B = 0
(iii) (A-B)U(ANB) = A
(v) A-(ANB) = A-B
(ii) AU(B - A) = AUB
(iv) (AUB) - B = A-B​

Answer 1

Step-by-step explanation:

Correct answer for

(iii) Since we can write A-B = A N B'

So. A = (A - B) U (A N B)

A = (A N B') U (A N B)

A = A N (BUB') A

A N U A = A

Hence Proved
