Math question: What is the sum of the digits in the number 8389?

To find the sum, we add the individual digits: 8 + 3 + 8 + 9 = 28.

Math question: What is the sum of the prime factors of the number 8389?

To find the prime factors of 8389, we need to divide it by prime numbers starting from 2. By observation, we can see that 8389 is a prime number itself since it is not divisible by any prime numbers less than its square root (√8389 ≈ 91.592). Therefore, the only prime factor of 8389 is 8389 itself. Thus, the sum of the prime factors of 8389 is simply 8389. Note: A prime number only has two factors: 1 and itself. In this case, since 8389 cannot be divided by any other prime numbers, it is considered a prime number. Therefore, there are no additional prime factors to consider, resulting in a sum of 8389 itself.

Math question: What is the sum of the digits in the number 8389?

To find the sum of the digits in 8389, we add the individual digits together. The digit 8 appears only once, so it contributes 8 to the sum. Similarly, the digit 3 contributes 3, the digit 8 contributes 8, and the digit 9 contributes 9. Thus, the sum of the digits in 8389 is 8 + 3 + 8 + 9 = 28.
