If A={x:x is a multiple of 3, x lt 12} and B={x: x in N, x^(2)-9x+18=0} then find A-B.

If A={x:x is a multiple of 3, x lt 12} and B={x: x in N, x^(2)-9x+18=0} then find A-B.

If A={x: x in N and x^(2)+x-2=0} and B={1} then find B-A.

If A={x: x in N and x^(2)+x-2=0} and B={1} then find B-A.

Let A={x:x in N , x^2-9=0}and B={x:x in Z , x^2-9=0} . Show that A ne B .

Let A={x in R,x^2-5x+6=0 and B={x:x in R,x^2=9} . Find (AuuB) and (AnnB)

If A = {x:x in N, (x^2-9)(x^2-5)=0} and B={x:x in N,x(x-2)(x-3)=0} where N is the set of all natural numbers, then BxxA is

Let A={x: x in R,x^2-5x+6=0} and B={x:x in R,x^2=9} Find A-B , B-A and verify that (A-B)uu(B-A)=(AuuB)-(AnnB) .
