Math question: What is the sum of the digits in the number 8509 when it is multiplied by 3, divided by 5, squared, and then subtracted by 100?

Let's solve this step by step. First, we multiply 8509 by 3, which gives us 25527. Then, we divide 25527 by 5 and get 5105.4. Squaring this number, we get approximately 26072501.16. Finally, subtracting 100 from this result provides us with 26072401.16. Thus, when the number 8509 undergoes these operations, the final answer is approximately 26072401.16.

Math question: What is the largest prime number less than 8509?

To find the largest prime number less than 8509, we start by checking if any number greater than 8509/2 is divisible by smaller numbers. By dividing 8509 by prime numbers starting from 2 and going up, we find that 8509 is not divisible evenly by any prime number less than its square root (√8509 ≈ 92.29). Therefore, 8509 itself is prime. Hence, the largest prime number less than 8509 is 8509.

Question: What is the least prime number that is a multiple of the sum of the digits of 8509?

To find the sum of the digits of 8509, we add 8 + 5 + 0 + 9 = 22. Therefore, we need to find the smallest prime number divisible by 22. By listing prime numbers, we find that 11 is the smallest prime that satisfies this condition. Hence, the answer is 11.
