Given:
D= a whole number
E= a perfect square less than 100
F= an even number between 10 and 20
solve-
D "U" E
"U" means union referring to sets

Since all perfect squares are whole numbers, then D "U" E is the same as D.
Thank you sinanissa, I corrected my error.

D = { 0, 1, 2, 3, 4,......}
E = {1, 4, 9, 16, 25, 36, 49, 64, 81}
The union of sets D and E is the set of whole numbers or the set of perfect squares less than 100 or the whole numbers that are perfect squares less than 100.
Every member of E is in D. That is, every perfect square less than 100 is a whole number.
Answer:
D"U"E = D
D"U"E = a whole number

What happened to F?
D U E is silly. Perfect squares are, by definition, whole numbers.
D U E = D

why did you mention F?
UNION means to combine not to subtract (for the first answerer).
the answer is D.
