That the set of perfect squares is closed under multiplication. That is if x and y are any two perfect squares, then x*y is a perfect square.
It is not possible to answer the question because the operator between C and (AintersectionB) is not visible.

because the monopolist firms are price maker and they can set any price they want and the customers are not perfect knowleged
That depends on that is in your set. ( However, 1/3 is always less than 1/2. )
Set of even numbers less than 50 and more than 40 = {42,44,46,48}
The sizes of the squares can vary with the size of the set.
