Math question: What is the sum of the digits when the number 1625 is multiplied by its double and then divided by the difference of its square and its triple?

To find the solution, we first multiply 1625 by 2, giving us 3250. Then we subtract three times 1625 from the square of 1625, which gives us 1625^2 - 3 * 1625 = 265625 - 4875 = 260750. Next, we divide 3250 by 260750, resulting in 0.01246732 (rounded to 8 decimal places). Now, we sum the digits of this decimal, which gives us 0+1+2+4+6+7+3+2 = 25. Hence, the sum of the digits is 25.

Math question: What is the sum of the prime factors of the number 1625?

To find the prime factors of 1625, we divide it by the smallest prime number, which is 5. This gives us 325. Dividing further by 5, we get 65. Dividing by 5 again, we obtain 13. Therefore, the prime factors of 1625 are 5, 5, and 13. Adding them up, we get 5 + 5 + 13 = 23. Hence, the sum of the prime factors of 1625 is 23.

Math Question: How many different prime factors does the number 1625 have?

To find the prime factors of 1625, we divide it successively by prime numbers. First, dividing by 5, we get 325, which further simplifies to 65 by dividing by 5 again. Then, dividing by 13 gives us 5. Finally, we're left with 5, which cannot be divided further. Thus, 1625 has three prime factors: 5, 5, and 13.
