Question 464862
Whenever you see a *[tex \cup] (union) of two sets, find all the elements that are in either or both sets. When you see a *[tex \cap] (intersection) of two sets, find all the elements that appear in both sets.


For example, 


*[tex \LARGE d) (A \cup B) \cap C = ({1,2,3} \cup {3,4,5,6}) \cap {3,5,7} = {1,2,3,4,5,6} \cap {3,5,7} = {3,5}] (make sure to follow the order of operations; do the parentheses first)


Sorry the { } symbols didn't appear, they are used everywhere in LaTeX to denote lots of other things, e.g. *[tex \sqrt{49}] is inputted as \sqrt{49}.
