Answer» udent,✩ GIVEN :P={m,N} and Q={a,b}____________________________✩ To FIND : PxQ and QxP_____________________________✩Explanation :P={a,b} Q={x,y,z} ☛ P×Q= {(a,x),(a,y),(a,z),(b,x),(b,y),(b,z)} ☛ Q×P= {(x,a),(x,b),(y,a),(y,b),(z,a),(z,b)}⇒By the definition of equality of ordered pairs, the pair (a,x) is not equal to the pair (x,a) THEREFORE, P×Q ≠ QxP |
