What exactly is the question
Assuming the universal set, E is the set of whole numbers, thus
E=S={...-2000, -1999, ...-2,-1,0,1,2,3,...1926, 1927...}
A={1,4,9,16,25,...}
B={2,4,6,8,...}
A'=complement, i.e. a set containing all members except A, therefore
A'=any whole number that is not a perfect square,
∪=union, combine two sets together.
A∪B=whole numbers that are either a perfect square or even
Can you figure out what is (A∪B)'?
