Math Question: Find the sum of the digits of the absolute difference between the reverse and square root of 2819.

To find the reverse of 2819, we switch the positions of its digits: 9128. Next, we calculate the square root of 2819, which is approximately 53.0543. The absolute difference between 9128 and 53.0543 is 9074.9457. Adding up the digits of this difference yields 9 + 0 + 7 + 4 + 9 + 4 + 5 + 7 = 45. Thus, the sum of the digits of the absolute difference is 45.

Math Question: What is the sum of the digits in the number 2819 and its square root raised to the power of the number of factors it has, minus the product of the tens digit and the ones digit?

To solve this question, we first sum the digits in 2819: 2 + 8 + 1 + 9 = 20. Next, we find the square root of 2819, which is approximately 53.06. Then, we calculate the number of factors of 2819, which is 4 (since it is a prime number). Now, we raise the square root to the power of the number of factors: 53.06^4 ≈ 121122.35. Finally, we multiply the tens digit (8) by the ones digit (9): 8 × 9 = 72. Subtracting the product from the previous result: 121122.35 - 72 = 121050.35. Hence, the answer is approximately 121050.35.

Math question: What is the sum of the individual digits in the number 2819?

To find the sum of the digits in 2819, we can break it down: 2 + 8 + 1 + 9 = 20. Hence, the sum of the digits in 2819 is 20.
