Math question: What is the sum of 6940 when divided by 4, the result when multiplied by 3, and then the square root is subtracted?

Let's work through the steps. Firstly, 6940÷4=1735. Next, 1735×3=5205. Finally, taking the square root of 5205 gives us approximately 72.12. Therefore, the answer is 72.12.

Math question: If 6940 is divided by 5 and then multiplied by 7, what is the resulting number?

To find the resulting number after dividing 6940 by 5 and multiplying by 7, we first divide 6940 by 5 which gives us 1388. Then, we multiply 1388 by 7 and get 9716. Therefore, the resulting number is 9716 derived from the given operations.

Math question: Find the sum of the digits of the number 6940 when each digit is raised to the power of its position in the number, and then multiplied by its position.

To find the sum, we calculate (6^1 * 1) + (9^2 * 2) + (4^3 * 3) + (0^4 * 4), which simplifies to 6 + 162 + 192 + 0, equalling 360. Thus, the sum of the digits of 6940, with their respective powers and positions considered, is 360.
