Firlakuza [10]
Answer:
![A\ u\ B\ n\ C = \{2\}](https://tex.z-dn.net/?f=A%5C%20u%5C%20B%5C%20n%5C%20C%20%3D%20%5C%7B2%5C%7D)
Step-by-step explanation:
Given
![A = \{1, 3, 5, 15\}](https://tex.z-dn.net/?f=A%20%3D%20%5C%7B1%2C%203%2C%205%2C%2015%5C%7D)
![B = \{2, 3, 5, 7\}](https://tex.z-dn.net/?f=B%20%3D%20%5C%7B2%2C%203%2C%205%2C%207%5C%7D)
![C = \{2, 4, 6, 8\}](https://tex.z-dn.net/?f=C%20%3D%20%5C%7B2%2C%204%2C%206%2C%208%5C%7D)

Determine (A U B) ∩ C
First, we calculate A u B
![A\ u\ B = \{1,3,5,15\} \ u\ \{2,3,5,7\}](https://tex.z-dn.net/?f=A%5C%20u%5C%20B%20%3D%20%5C%7B1%2C3%2C5%2C15%5C%7D%20%5C%20u%5C%20%5C%7B2%2C3%2C5%2C7%5C%7D)
This means that we bring A and B together without repetition.
![A\ u\ B = \{1,2,3,5,7,15\}](https://tex.z-dn.net/?f=A%5C%20u%5C%20B%20%3D%20%5C%7B1%2C2%2C3%2C5%2C7%2C15%5C%7D)
Next:
![A\ u\ B\ n\ C = \{1,2,3,5,7,15\}\ n\ \{2,4,6,8\}](https://tex.z-dn.net/?f=A%5C%20u%5C%20B%5C%20n%5C%20C%20%3D%20%5C%7B1%2C2%2C3%2C5%2C7%2C15%5C%7D%5C%20n%5C%20%5C%7B2%2C4%2C6%2C8%5C%7D)
This means that we only get the common items
![A\ u\ B\ n\ C = \{2\}](https://tex.z-dn.net/?f=A%5C%20u%5C%20B%5C%20n%5C%20C%20%3D%20%5C%7B2%5C%7D)
