Question: What is the sum of the digits in the number 847, when each digit is multiplied by its position value and squared, then added together?

To find the sum of the digits in the number 847, we multiply each digit by its position value and square the result. First, let's separate the digits: 8, 4, and 7. Now, we multiply the first digit, 8, by its position value of 1, and square the result: (8 * 1)^2 = 64. Next, the second digit, 4, is multiplied by its position value of 10, and squared: (4 * 10)^2 = 1600. Lastly, the third digit, 7, is multiplied by its position value of 100, and squared: (7 * 100)^2 = 490000. To get the final result, we add all the squared values together: 64 + 1600 + 490000 = 491664. Thus, the sum of the digits in the number 847, when each digit is multiplied by its position value and squared, is 491664.

Math Question: What is the sum of the digits of the number obtained by multiplying 847 by 3 and then subtracting the result from the square of 847?

To find the sum of the digits of the resulting number, let's first multiply 847 by 3, yielding 2541. Then, square 847, resulting in 717409. Now, subtract the previous product from the squared number: 717409 - 2541 = 714868. The sum of the digits, 7 + 1 + 4 + 8 + 6 + 8, equals 34. Therefore, the sum of the digits obtained by multiplying 847 by 3 and subtracting it from the square of 847 is 34.

Math Question: If the number 847 is divided by 7, what is the remainder?

To determine the remainder when 847 is divided by 7, we divide 847 by 7 using long division. The dividend is 847, and the divisor is 7. When we divide, the quotient is 121 and the remainder is 0. Therefore, the remainder when 847 is divided by 7 is 0. This means that 847 is divisible by 7 without any remainder.
