Question

Exercise 1.1
1. Find AXB, AXA and BXA
(i) A={2-2,3) and B={1.-4} (ii) A=B={p.q} (iii) A={m.n}; B=0
2. Let A = {1,2,3) and B = {rx is a prime number less than 10}. Find A B and Bx A.
3. If BX A = {(-2,3).(-2,4),(0,3),(0,4),(3,3),(3,4)} find A and B.
4. If A = {5,6), B = {4,5,6), C = {5,6,7}, Show that AXA = (BxB) (CⓇC).
5. Given A={1,2,3), B = {2,3,5), C = {3,4} and D = {1,3,5), check if
(ANC)*(BOD) = (AB) n(C x D) is true?
6. Let A = {1 € W x<2}, B = {x eNi<< < 4) and C = {3,5). Verify that
(i) AX(BUC) = (A x B)U(AXC) (ii) Ax(BNC)=(A x B) n(AXC)
(iii) (AUB)X = (AXC) U(BXC)
7. Let A = The set of all natural numbers less than 8, B = The set of all prime numbers
less than 8, C = The set of even prime number. Verify that
(i) (ACB) x C = (AxC)n(BxC) (ii) AX(B-C)=(AⓇB) -(AXC)
