[" EXAMPLE7Let A and B be sets,if "A nn X=B nn X=phi" and "A uu X=B uu X" for some set "X" ,prove that "],[A=B" ."]

Let A and B be sets.If A nn X=B nn X=phi and A uu X=B uu X for some set X then how that A=B

Let A and B be sets .If A nn X=B nn X=O/ and Auu X=B uu X for some set X,then show that A=B.

Let A and B be sets. If A nn X = B nn X =phi and A uu X = B uu X for some set X, show that A = B. (Hints A = A nn (A uu X) , B=B nn (B uu X) and use Distributive law )

Let A and B be two sets.If X is any set such that A nn X=B nn X and A uu X=B uu X then.

If A and B are sets and A uu B = A nn B then

If A,B and C are three sets such that A nn B= A nn C and A uu B=A uu C , then :

If A and B are two sets , then A nn (A uu B) equals :

If A and B are two sets , then A nn (A uu B) equals :
