To solve the problem based on the uploaded image, let's analyze the given sets and determine the result for the operation $\overline{A}$, which is the complement of $A$ relative to the universal set $U$.

Given Sets:

• $U = \{0, 1, 2, 3, 4, 5, 6, 7, 8, 9\}$
• $A = \{2, 4, 6, 8\}$

The complement of $A$ ($\overline{A}$) consists of all elements in $U$ that are not in $A$.

Steps:

1. Identify all elements of $U$: $\{0, 1, 2, 3, 4, 5, 6, 7, 8, 9\}$.
2. Remove elements of $A = \{2, 4, 6, 8\}$ from $U$.

Calculation:

The elements remaining in $U$ after removing $A$ are: $\{0, 1, 3, 5, 7, 9\}.$

Result:

The complement of $A$ is: $\overline{A} = \{0, 1, 3, 5, 7, 9\}.$

In the required format (numbers without spaces or commas, in ascending order): $\text{Answer: } 013579$

Let me know if you need further clarification!

Related Questions:

1. What is the complement of $B$ relative to $U$?
2. What is the union of $A$ and $B$?
3. What is the intersection of $A$ and $C$?
4. How do you find the difference between two sets (e.g., $A \setminus B$)?
5. How can we verify if a set is a subset of another?

Tip:

When calculating complements, always work within the universal set $U$ and exclude the elements explicitly stated in the subset.
