Math question: What is the sum of the digits of the number 1043?

To find the sum of the digits of 1043, we add the individual digits together. Since 1 + 0 + 4 + 3 = 8, the sum of the digits of 1043 is 8.

Math question: If you subtract 297 from a number and then multiply the result by 3, you get 3129. What is the original number?

Let's assume the original number is x. Based on the given information, we can form an equation: (x - 297) * 3 = 3129. Expanding the equation, we have 3x - 891 = 3129. Solving for x, we add 891 to both sides to get 3x = 4020. Dividing both sides by 3, we find x = 1340. Therefore, the original number is 1340.

Math question: What is the square root of the sum of 1043 squared and the square of the next prime number greater than 1043?

To solve this, we find that 1043 squared equals 1087249. The next prime number greater than 1043 is 1049. Thus, we have to find the square root of the sum of 1087249 and 1049 squared, which is 1087249 + 1049^2 = 1087249 + 1100401 = 2187650. Taking the square root of 2187650, we get the result of 1479.903711. Therefore, the square root of the sum is approximately 1479.9.
