Math question: What is the sum of the digits in the number 1329 when each digit is raised to the power of its position in the number?

To find the sum of the digits, we take each digit (1, 3, 2, and 9), raise it to its respective position (1, 2, 3, and 4), and then add them all together. So, it becomes (1^1) + (3^2) + (2^3) + (9^4) = 1 + 9 + 8 + 6561 = 6579. Therefore, the sum of the digits in 1329, each raised to the power of its position, is 6579.

Math question: Find the sum of the digits of the number 1329 that are divisible by both 3 and 7.

To solve this, we need to identify the digits that are divisible by both 3 and 7. In 1329, only the digit 3 meets this criteria. Thus, the sum of the digits is 3.

Math question: What is the smallest prime factor of the number obtained by multiplying 1329 with its reverse?

To find the number obtained by multiplying 1329 with its reverse, we first reverse 1329 to get 9231. Multiply these two numbers: 1329 * 9231 = 12270599. Now, we need to find the smallest prime factor of 12270599. By applying various methods like trial and error, we find that the smallest prime factor is 7. Thus, the smallest prime factor of the number obtained by multiplying 1329 with its reverse (12270599) is 7.
