Question: Given the number 3947, what is the sum of its digits when multiplied by its square root, divided by the difference between its tens and units digit, rounded to the nearest whole number?

To find the sum of the digits, we have 3 + 9 + 4 + 7 = 23. The square root of 3947 is approximately 62.85. The difference between the tens and units digit is 9 - 7 = 2. Dividing 23 by 2 gives us 11.5, rounding it to the nearest whole number results in 12. Therefore, when multiplying the sum of the digits by the square root and dividing by the difference between tens and units digit, we get 12.

Question: What is the product of 3947 and the sum of its digits when multiplied by 3 and divided by 2, subtracted from the square root of the sum of 3947 and 100?

Let's calculate step by step. The sum of the digits in 3947 is 3 + 9 + 4 + 7 = 23. The product of 3947 and the sum of its digits (23) when multiplied by 3 is 364911. After dividing by 2, we get 182455.5. The sum of 3947 (our initial number) and 100 is 4047. Taking the square root of 4047 yields approximately 63.643. Finally, subtracting 182455.5 from 63.643 gives us approximately -182392.857. Therefore, the answer is -182392.857.

Math question: What is the sum of the digits of the number 3947?
