Question: What is the sum of the digits when 8145 is multiplied by its reversed number, and then added to the product of its individual digits?

To find the product of the digits, the number 8145 is decomposed into 8, 1, 4, and 5. The product of 8, 1, 4, and 5 is 160. Now, multiplying 8145 by its reversed number (5418), we get 44,121,510. By summing the digits of this result (4+4+1+2+1+5+1+0 = 18), we find a sum of 18. Lastly, adding the product (160) to the sum (18), we obtain a final result of 178.

Math question: What is the smallest positive multiple of 8145 that is also a perfect cube?

To find the smallest positive multiple of 8145 that is a perfect cube, we need to prime factorize 8145. The prime factorization of 8145 is 3 * 5 * 7 * 49. As we see, the prime factor 7 is repeated twice, making it a perfect cube. Hence, the smallest positive multiple of 8145 that is a perfect cube would be 7 * 49 = 343.

Math question: What is the sum of the digits of the number 8145?

To find the sum of the digits, we add each digit of 8145 individually. The digit 8 contributes 8, the digit 1 contributes 1, the digit 4 contributes 4, and the digit 5 contributes 5. Adding these together, we get 8 + 1 + 4 + 5 = 18. Therefore, the sum of the digits of 8145 is 18.
