Let `U` be the universal set, where:
`U = \{1,2,3,4,5,6,7,8,9,10\}`
Let sets `A, B` and `C` be subsets of `U`, where:
`A = \{1,2,4,9\}` , `B= \{5,8,9\}` , and `C = \{1,4,5,6,7\}`
Find `A \cup (B \cap C): \{` `\}`
Find `(A \cup B) \cap (A \cup C): \{` `\}`
Enter the elements as a list, separated by commas in order from smallest to largest. If the result is the empty set, enter DNE
