From the image, I can identify a mathematical problem involving sets $A$ and $B$ defined as:

• $A = \{4, 7\}$
• $B = \{3, 6\}$

It appears that the problem asks to compute various set operations between $A$ and $B$ such as union ($A \cup B$), intersection ($A \cap B$), difference ($A \setminus B$ and $B \setminus A$), symmetric difference ($A \Delta B$), and possibly set complements.

Let’s go through the operations one by one:

1. Union ($A \cup B$): The union of two sets includes all elements that are in either set. $A \cup B = \{4, 7\} \cup \{3, 6\} = \{3, 4, 6, 7\}$

2. Intersection ($A \cap B$): The intersection includes only elements common to both sets. $A \cap B = \{4, 7\} \cap \{3, 6\} = \emptyset \quad (\text{no common elements})$

3. Difference ($A \setminus B$): The difference consists of elements in $A$ that are not in $B$. $A \setminus B = \{4, 7\} \setminus \{3, 6\} = \{4, 7\}$

4. Difference ($B \setminus A$): The difference consists of elements in $B$ that are not in $A$. $B \setminus A = \{3, 6\} \setminus \{4, 7\} = \{3, 6\}$

5. Symmetric Difference ($A \Delta B$): The symmetric difference includes elements in either $A$ or $B$, but not in both. $A \Delta B = (\{4, 7\} \setminus \{3, 6\}) \cup (\{3, 6\} \setminus \{4, 7\}) = \{4, 7\} \cup \{3, 6\} = \{3, 4, 6, 7\}$

Would you like me to go into further details on any of these operations or clarify any particular part?

Here are 5 related questions:

1. What is the complement of a set, and how is it calculated?
2. Can the union of two sets ever result in a set smaller than either of the original sets?
3. How does the intersection of two sets relate to their symmetric difference?
4. In what cases will the symmetric difference be equivalent to the union of two sets?
5. How can set operations be applied to solve real-world problems, such as in databases?

Tip: Always remember that the union of sets includes all unique elements, while the intersection focuses only on common elements.
