Math question: If the number 6781 is multiplied by 8 and then divided by the sum of its digits, what is the resulting value?

To solve this, we first find the sum of the digits: 6 + 7 + 8 + 1 = 22. Now, multiply 6781 by 8: 6781 * 8 = 54248. Finally, divide the product by the sum of the digits: 54248 / 22 = 2465.3636 (rounded to 4 decimal places). Therefore, the resulting value is approximately 2465.3636.

Math Question: What is the sum of the individual digits of the square root of 6781, rounded to the nearest whole number?

To find the square root of 6781, we get approximately 82.377. The sum of its individual digits (8 + 2 + 3 + 7 + 7) equals 27. Rounding this to the nearest whole number gives us the final answer, which is 27.

Math question: What is the product when the number 6781 is multiplied by 3 and divided by 4, and then added to the square root of 6781?

To find the product, we need to perform the following steps. Firstly, multiply 6781 by 3, which gives us 20343. Then, divide this result by 4, resulting in 5085.75. Finally, find the square root of 6781, giving us approximately 82.345. Now, we add 5085.75 and 82.345 to get 5168.095. Therefore, the answer to the question is 5168.095.
