Math question: What is the smallest prime number greater than 1000 that is also a multiple of 13?

The smallest prime number greater than 1000 is 1009, but it's not a multiple of 13. Therefore, we need to find the next prime number. Adding 13 repeatedly to 1009, we get 1022, 1035, 1048, which is not prime. However, adding 13 to 1048, we get 1061, which is prime. Hence, the answer is 1061, the smallest prime number greater than 1000 and a multiple of 13.

Math question: What is the sum of 1042 and the product of its digits squared, divided by the difference between the last two digits of 1042 and their product, all multiplied by the square root of 1042?

To solve this, we begin by finding the digits of 1042: 1, 0, 4, and 2. We square each digit and find their sum: (1^2 + 0^2 + 4^2 + 2^2) = (1 + 0 + 16 + 4) = 21. The last two digits of 1042 are 4 and 2. Their product is 4 * 2 = 8. The difference between the last two digits and their product is 42 - 8 = 34. The square root of 1042 ≈ 32.28. Thus, we can now calculate the final result: (1042 + 21) / 34 * 32.28 ≈ 64.01. Therefore, the answer is approximately 64.01.

Math Question: What is the sum of the digits of 1042 plus the product of its first and last digit squared, divided by the difference between the first and third digit?

To find the sum of the digits of 1042, we add 1 + 0 + 4 + 2, which equals 7. The first digit is 1, and the last digit is 2. Square both, resulting in 1² + 2² = 1 + 4 = 5. The difference between the first and third digit is 1 - 4 = -3. Therefore, the expression becomes (7 + 5) / -3 = 12 / -3 = -4. Thus, the answer is -4.
