From the image, the problem involves finding the intersection of two sets, $A \cap B$. Here's the detailed solution:

Sets provided:

• $U = \{0, 1, 2, 3, 4, 5, 6, 7, 8, 9\}$ (Universal set)
• $A = \{2, 4, 6, 8\}$
• $B = \{2, 3, 4, 5\}$
• $C = \{1, 3, 5, 7, 9\}$ (not relevant for this task)

Operation:

We need to calculate: $A \cap B$

Intersection rule:

The intersection of two sets consists of elements that are common to both sets.

Step-by-step process:

1. Elements in $A$: $\{2, 4, 6, 8\}$
2. Elements in $B$: $\{2, 3, 4, 5\}$
3. Common elements between $A$ and $B$: $\{2, 4\}$

Result:

The intersection $A \cap B = \{2, 4\}$.

Final answer:

Write the elements in increasing order without spaces or commas:
24

Do you have any additional questions or need further clarification?
Here are 5 related questions for practice:

1. What is $B \cap C$?
2. What is $A \cup B$ (union of $A$ and $B$)?
3. If $D = \{0, 4, 6\}$, what is $A \cap D$?
4. How many subsets does $A$ have?
5. If $U$ is the universal set, what is $A'$ (the complement of $A$)?

Tip: The intersection of sets always contains elements that are part of both sets, never outside.
