Question: What is the sum of the digits of the number 2689 when each digit is squared and multiplied by its position in the number, starting from the left? Explanation: To solve this, we square each digit (2^1 = 2, 6^2 = 36, 8^3 = 512, and 9^4 = 6561) and multiply it by its position. Adding these products together (2*1 + 36*2 + 512*3 + 6561*4) gives the answer.

The sum is 52198. When squaring and multiplying each digit by its position, the sum of these products evaluates to 52198.

Math question: If the number 2689 is multiplied by 3, added to 743, and then divided by 7, what is the final result?

To solve this problem, we first multiply 2689 by 3, which gives us 8067. Next, we add 743 to this result, resulting in 8810. Finally, we divide 8810 by 7, giving us 1258.57 (rounded to two decimal places). Therefore, the final result is approximately 1258.57.

Question: What is the sum of the digits in the number 2689, when the digits are multiplied by their respective place values and added together?

To find the sum of the digits in 2689, we multiply each digit by its place value and add them up. Number: 2689 2000s 600s 80s 9s 2 x 1000 = 2000 6 x 100 = 600 8 x 10 = 80 9 x 1 = 9 ----------------------------------- Total Sum: 2000 + 600 + 80 + 9 = 2689 Hence, the sum of the digits in the number 2689, when the digits are multiplied by their respective place values and added together, is 2689.
