Using laws of set algebra, show that `If A' uu B = U`, show that `A subB`

If A^(c) uu B=U , show that A sub B .

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

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

*' is a binary operation defined on Q (set of rational numbers) such that a * b = ab/3, show that : (a * b) * c = a * (b * c).

If A and B are two sets such that A sub B , then what is A uu B ?

Let A and B be sets, show that f : A xx B rarr B xx A such that f(a,b) = (b,a) is a bijective function.

Let A , B and C be the sets such that A uu B=A uu C and A nn B = A nn C . show that B=C

Let A = {a,e,i, o, u} and B= {a, i, u}. Show that A uu B=A .

If A and B are subsets of the universal set U, then show that : (A nn B) sub B .
