The image contains a set theory problem in Indonesian. The problem asks for a Venn diagram to represent the universal set \( U \) and the sets \( A \) and \( B \), and then to solve specific set operations. Here's the provided information:

- Universal set \( U = \{1, 2, 3, 5, 6, 7, 8\} \)
- Set \( A = \{2, 3, 5, 7\} \)
- Set \( B = \{1, 3, 4, 7, 8\} \)

You are asked to solve the following set operations:
1. \( A - B \)
2. \( B - A \)
3. \( A \cap B \)
4. \( A \cup B \)
5. \( A \cap B' \) (complement of B with respect to U)
6. \( B \cap A' \) (complement of A with respect to U)

Let me start solving them one by one:

### 1. \( A - B \) (Elements in \( A \) but not in \( B \))
- \( A - B = A \setminus B = \{2, 3, 5, 7\} \setminus \{1, 3, 4, 7, 8\} = \{2, 5\} \)

### 2. \( B - A \) (Elements in \( B \) but not in \( A \))
- \( B - A = B \setminus A = \{1, 3, 4, 7, 8\} \setminus \{2, 3, 5, 7\} = \{1, 4, 8\} \)

### 3. \( A \cap B \) (Intersection of \( A \) and \( B \))
- \( A \cap B = \{2, 3, 5, 7\} \cap \{1, 3, 4, 7, 8\} = \{3, 7\} \)

### 4. \( A \cup B \) (Union of \( A \) and \( B \))
- \( A \cup B = \{2, 3, 5, 7\} \cup \{1, 3, 4, 7, 8\} = \{1, 2, 3, 4, 5, 7, 8\} \)

### 5. \( A \cap B' \) (Elements in \( A \) and not in \( B \), i.e., the complement of \( B \) with respect to \( U \))
- \( B' = U \setminus B = \{1, 2, 3, 5, 6, 7, 8\} \setminus \{1, 3, 4, 7, 8\} = \{2, 5, 6\} \)
- \( A \cap B' = \{2, 3, 5, 7\} \cap \{2, 5, 6\} = \{2, 5\} \)

### 6. \( B \cap A' \) (Elements in \( B \) and not in \( A \), i.e., the complement of \( A \) with respect to \( U \))
- \( A' = U \setminus A = \{1, 2, 3, 5, 6, 7, 8\} \setminus \{2, 3, 5, 7\} = \{1, 6, 8\} \)
- \( B \cap A' = \{1, 3, 4, 7, 8\} \cap \{1, 6, 8\} = \{1, 8\} \)

Would you like to see the Venn diagram representation as well?

Here are five related questions that could expand your understanding of this topic:
1. What is the difference between \( A \cup B \) and \( A \cap B \)?
2. How would the results change if set \( A \) included elements not in the universal set \( U \)?
3. Can you calculate \( (A \cup B)' \) with respect to \( U \)?
4. How does the complement of a set affect its intersection with another set?
5. What does the symmetric difference between \( A \) and \( B \) represent?

**Tip**: The complement of a set with respect to the universal set contains all the elements of the universal set that are not in the original set. This is a useful concept when working with Venn diagrams and set operations.

This problem involves solving basic set operations (A - B, B - A, A ∩ B, A ∪ B, A ∩ B', B ∩ A') using Venn diagrams with universal set U = {1, 2, 3, 5, 6, 7, 8}, A = {2, 3, 5, 7}, and B = {1, 3, 4, 7, 8}. Suitable for students in Grades 9-11.
