Answer

The elements in the set $(D \cup E) \cap F$ are $\boxed{10, 11, 13}$.

Steps

Step 1 ：Let $D=\{8,11,13\}, E=\{8,10,11,12\}$ and $F=\{7,9,10,11,13\}$.

Step 2 ：Find the union of D and E, which is $D \cup E = \{8, 10, 11, 12, 13\}$.

Step 3 ：Find the intersection of the result with F, which is $(D \cup E) \cap F = \{10, 11, 13\}$.

Step 4 ：The elements in the set $(D \cup E) \cap F$ are $\boxed{10, 11, 13}$.
