Math question: What is the cube root of the sum of the square root of 7925 and the product of its digits?

To solve this, let's break it down. The square root of 7925 is approximately 89. No two digits of 7925 multiply together, so the product of its digits is 7 × 9 × 2 × 5 = 630. The sum of the square root and the product is 89 + 630 = 719. Now, to find the cube root of 719, we can use trial and error. Starting with the guess of 9, cube it to get 729. Lowering the guess slightly, let's try 8. Cube it to get 512. 7 < 512 < 719. Hence, the cube root of 719 is between 8 and 9. After further calculations, it can be approximated to 8.94, which is our answer.

Math question: If the number 7925 is multiplied by the sum of its digits minus their difference and then divided by the product of its digits, what is the result?

To find the solution, we first calculate the sum of the digits, which is 7 + 9 + 2 + 5 = 23, and the difference, which is 7 - 9 - 2 - 5 = -9. Then, we find the product of the digits, which is 7 * 9 * 2 * 5 = 630. Now, we multiply 7925 by (23 - (-9)) and divide it by 630. Simplifying, we have 7925 * (23 + 9) / 630 = 7925 * 32 / 630 = 402400 / 630 = 639.68. Thus, the result is approximately 639.68.

Math question: What is the sum of the digits of the number formed by alternating 7925 five times?

The number formed by alternating 7925 five times is 7925792579257925. To find the sum of its digits, we add 7+9+2+5+7+9+2+5+7+9+2+5+7+9+2+5 = 101. Therefore, the sum of the digits is 101.
