Find ` A xx B ,A xx A and B xx A`
` A= {2,-2,3},B ={1,-4}`

Find A xx B ,A xx A and B xx A A =B= {p,q}

When Will A xx B be equal to B xx A

If n (A xx B) =24 and A = {1,3,5,7} then n (B) is

Let A={1,2}, B={1,2,3,4}, C={5,6} and D={5,6,7,8}. Verify that (i) A xx (B cap C)=(A xx B) cap (A xx C), (ii) A xx C is a subset of B xx D

Let A and B are two sets such that n(A) = 3 and n(B) =2 . If (x,1) , (y,2) and (z,1) are in A xx B , find A and B where x,y, z are distinct elements.

If n (A xx B) = 6 and A = {1,3} then n (B) .............. .

If n((A xx B) nn (A xx C))=8 and n(B nnC) = 2 then n(A) ……………… .

If A = {1,2,3,4} and B = {3,4,5,6}, find n ((A cupB) xx (A cap B) xx (A Delta B)) .
