(iv)quad A uu B=A nn B hArr A=B

For any two sets A and B, prove that A uu B=A nn B hArr A=B

A uu B = A nn B iff :

If A uu B=A nn B, prove that A=B

Prove that A uu B= A nn B implies A=B.

Show that A uu B=A nn B implies A=B

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

Prove A nn B=A and A uu B=A rArr A=B

Prove the following,for sets A,B,C(i)A sube B,B sube C rArr A sube C(ii)A sube B hArr A uu B=B,A sube B hArr A nn B=A

Using properties of sets, show that (i) A uu ( A nn B) = A (ii) A nn (A uu B) =A .
