Question: What is the product of 398 multiplied by the sum of its digits, divided by the difference between the largest and smallest digit of 398?

To find the product of 398 multiplied by the sum of its digits, we need to add the digits of 398, which are 3, 9, and 8, resulting in 20. Next, we calculate the difference between the largest (9) and smallest (3) digit of 398, which is 6. Now, dividing the product of 398 and its digit sum (398 * 20 = 7960) by the digit difference (7960 ÷ 6), we get 1326.66 recurring. Therefore, the answer is approximately 1326.66 when rounded to two decimal places.

Math question: What is the sum of the digits of the number 398?

To find the sum of the digits of 398, we break it down into its constituent digits: 3, 9, and 8. Then we add these digits together: 3 + 9 + 8 = 20. Hence, the sum of the digits of the number 398 is 20.

Question: What is the difference between the sum of the digits of 398 and the sum of the prime factors of its square?

To find the sum of the digits in 398, we add 3 + 9 + 8 which equals 20. To find the square of 398, we multiply it by itself: 398 * 398 = 158,404. The prime factors of 158,404 are 2, 7, 41, and 157. Adding these prime factors together gives us 2 + 7 + 41 + 157 = 207. Finally, we subtract the sum of the digits (20) from the sum of the prime factors (207) and get 207 - 20 = 187. Therefore, the difference between the sum of the digits of 398 and the sum of the prime factors of its square is 187.
