Question: If 9904 is divisible by a 3-digit number N, where N is a multiple of 8 and the sum of its digits is a prime number, what is the value of N?

N must be a multiple of 8, so it could be 16, 24, 32, ... 248. Considering the sum of digits, N can be 16 (1+6=7), 32 (3+2=5), 56 (5+6=11), 64 (6+4=10), 104 (1+0+4=5), 176 (1+7+6=14), 224 (2+2+4=8), or 248 (2+4+8=14). However, prime-sum conditions narrow it down to 56 or 224. Testing divisibility, we find 9904 is divisible by 56 but not by 224. Thus, N = 56.

Math Question: What is the sum of the digits of the product of 9904 and its reverse?

To find the solution, we multiply 9904 by its reverse, which is 4009. The product of these numbers is 39,696,736. Now, we add up the individual digits: 3 + 9 + 6 + 9 + 6 + 7 + 3 + 6 equals 49. Therefore, the sum of the digits of the product of 9904 and its reverse is 49.

Math question: What is the square root of the sum of the square of 9904 and the cube root of 9904? (200 characters)

To find the square root, we first calculate 9904 squared (98192016) and then take its cube root (45.0202). Adding this to 9904, we get 98292020. Taking the square root of this gives 9914.8749. Therefore, the answer is approximately 9914.8749. (429 characters)
