What is the sum of the digits of the number 3791 multiplied by the number itself, divided by the square of the product of its first and last digits, plus the remainder when dividing the product of its second and third digits by its fourth digit, subtracted by the product of its second and fourth digits?

To find the sum of the digits, 3+7+9+1 = 20. The number multiplied by the sum is 3791*20 = 75820. The product of the first and last digits is 3*1 = 3, so the square of it is 3^2 = 9. Thus, 75820/9 = 8424.4444. The product of the second and third digits is 7*9 = 63. When divided by the fourth digit (1), the remainder is 63%1 = 0. Finally, subtracting the product of the second and fourth digits (7*1 = 7) from 0 gives 0-7 = -7. Therefore, the result is -7.

Math question: What is the sum of all the digits in the number 3791?

To find the sum of all the digits in 3791, we add each digit individually. 3 + 7 + 9 + 1 = 20. The sum of all the digits in 3791 is 20.

Math question: What is the sum of the digits of 3791 when each digit is raised to the power of its respective place value?

To find the sum of the digits, let's break down 3791. The digit 3 is in the thousands place, so it equals 3^3 = 27. The digit 7 is in the hundreds place, so it equals 7^2 = 49. The digit 9 is in the tens place, so it equals 9^1 = 9. Lastly, the digit 1 is in the units place, so it equals 1^0 = 1. Adding these values together, we get 27 + 49 + 9 + 1 = 86. Hence, the sum of the digits of 3791, when each digit is raised to the power of its respective place value, is 86.
