Question: What is the sum of the digits of the number 9819 multiplied by the square root of the number 9819?

To find the sum of the digits of the number 9819, we add 9 + 8 + 1 + 9 = 27. Now, multiplying this sum (27) by the square root of 9819, we get 27 * √9819 ≈ 980.34 (rounded to two decimal places). Therefore, the final answer is approximately 980.34.

Question: What is the largest prime factor of the number 9819?

To find the largest prime factor of 9819, we start by checking if 2 is a factor. However, 9819 is an odd number, so it is not divisible by 2. Next, we divide 9819 by 3 to get 3273, which is divisible by 3. Continuing this process, we divide 3273 by 3 again to get 1091, and further divide 1091 by 7 to obtain 13 as the final quotient. Since 13 is a prime number, it is the largest prime factor of 9819. Therefore, the largest prime factor of 9819 is 13.

What is the sum of the digits when the number 9819 is multiplied by the difference between the largest and smallest prime numbers up to 20?

To find the difference between the largest and smallest prime numbers up to 20, we subtract 2 from 19, which gives us 17. Now, multiplying 9819 by 17, we get 167223. Adding up the digits of 167223, we have 1 + 6 + 7 + 2 + 2 + 3 = 21. Hence, the answer is 21.
