1. The problem asks whether the prime factors of 99 are 9 and 11. 2. Prime factors are prime numbers that multiply together to give the original number. 3. First, factorize 99 into its prime factors. 4. 99 can be divided by 3: $$99 \div 3 = 33$$ 5. Then, 33 can be divided by 3 again: $$33 \div 3 = 11$$ 6. Now, 11 is a prime number. 7. So, the prime factors of 99 are 3, 3, and 11. 8. Note that 9 is not a prime number because it can be factored into 3 \times 3. 9. Therefore, the statement that the prime factors of 99 are 9 and 11 is false. 10. The correct prime factors of 99 are 3, 3, and 11.
