" (iii) If "A={1,2},B={3,4}," then "A times(B nn phi)=phi

If A={(1,2)},B={(3,4)}, then A xx(B xx phi)=

State whether the following statement is true or false. If the statement is false, rewrite the given statement correctly. If A = {1, 2}, B = {3, 4}, then A xx (B nn phi) = phi .

State whether each of the following statetments is true or false. If the statement is false, rewrite the given statement correctly. If A ={1,2}, B = {3,4} then A xx ( B cap phi) = phi

If A = {1,2,3}, B= {3,4,5}, then (A nn B) xx A is

If A = {1, 2, 3}, B = {3, 4, 5}, then (A nn B) xx A is

If A = {1, 2, 3}, B = {3, 4, 5}, then (A nn B) xx A is

A= {1,2,3,4} , B={3,4,5} then (A xx B)nn (B xx A)=

If A=(1,2,3) ,B=(4,5,6) and C=(1,2) then (A nn B) times(A nn C) is

Prove that : (A-B) nn (B-A)=phi .
