The set "ans" is defined as {x: x is an even number, x < 10}. To list the elements of this set, we need to find all even numbers that are less than 10.
1. Identify even numbers less than 10:
- The even numbers less than 10 are 2, 4, 6, and 8. These numbers satisfy the condition of being even (divisible by 2) and less than 10.
2. List the elements of the set "ans":
- The set "ans" contains the even numbers less than 10, which are 2, 4, 6, and 8.
- Therefore, the elements of the set "ans" can be listed as {2, 4, 6, 8}.
In conclusion, the elements of the set "ans" are 2, 4, 6, and 8, as these numbers are even and less than 10 based on the given condition.
