If `A = {a,e,i,o,u}, B= {a,b,c}` then find `A∪B ` and `A∩B`?

If A={a,e,i,o,u},B={a,b,c} then find A uu B and A nn B

If A={a,e,I,o,u} , B={b,c,d} , then find (A-B)nnB .

Prove that A uu B=A nn B if and only if A=B If A={a,e,i,o,u},B={b,c,d} then find (A-B).

If A = { a,e,I,o,u } and B = {a,I,u} , then AuuB = ……………

If A={a,e,I,o,u} and B={a,I,e,c,d } then n(A-B) is ______.

Let A = { a , e , i , o, u} and B = { a , b , c , d)dot Is A a subset of B? No.(Why?). Is B a subset of A? No. (Why?)

Let A={a,e,I,ou} and B= {a,u}. Show that AuuB=A .
