To determine which numbers from the provided list are prime, let's define prime numbers. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Now, let's analyze the numbers given:
- 9: Not prime (divisible by 1, 3, and 9)
- 11: Prime (only divisible by 1 and 11)
- 19: Prime (only divisible by 1 and 19)
- 29: Prime (only divisible by 1 and 29)
- 39: Not prime (divisible by 1, 3, 13, and 39)
Therefore, the prime numbers from the list are: 11, 19, 29.
