Given D = {x | x is a whole number}. E = {x | x is a perfect square between 49 and 100}. F = {x | x is an even number between 10 and 20}. 1.The expression D∪F means (64 and 81) OR (all whole numbers). 2.The expression D∩F means (16,22,24,18) OR (12,14,16,18). 3.The expression D∩E means (all whole numbers) OR (64,81). 4.The expression E∩F means (all whole numbers) OR (empty set). 5.The expression D∩(E∪F) means (empty set) OR (81,64,12,14,16,18)

DUF is all whole numbers because the definition of a union is the set that contains both sets.

DNF means (16,22,24,18) because an intersection is the common numbers between the sets

DNE means (64,81)

ENF is an empty set

DN(EUF)= (81,64,12,14,16,18)

Good luck I hate sets and set proofs
