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

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

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

Let V = { a, e, i, o, u } and B = { a, i, k, u} . Find V – B and B – V

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