Answer
$J \cup L$ = 2, 4, 5, 6, 7, 8, 10
Work Step by Step
We know that the union of the two sets includes all elements that are in either set, while the intersection only includes elements that are in both sets. Thus:
$J \cup L$ = 2, 4, 5, 6, 7, 8, 10
Note that the elements of L are: 2, 4, 6, 8, 10
