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.

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

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

If a,b,c are in G.P and a^(1/x) = b^(1/y) = c^(1/z) , prove that x,y,z are in A.P.

Given that x+y+z=15w h e na ,x ,y ,z ,b are in A.P. and 1/x+1/y+1/z+=5/3w h e n a ,x ,y ,z ,b are in H.P.

If A xx B={(a, x), (a,y),(b,x),(b,y)} . Find A and B.

Let A = {x, y, z) and B = {1, 2}. Find the number of relations from A to B.

Let Z denote the set of all integers and A = { (a,b) : a^2 +3b^2 = 28 ,a,b in Z } and B= {(a,b ):a gt b, in Z} . Then the number of elements in A nn B is

Let A = { x | x in N,x le 4 } , B ={ y|y in N, y le 3 } Represent A xx B and B xx A in a graph sheet . Can you see the difference between A xx B and B xx A
