Math question: What is the square root of the sum of 8905 and its double, divided by the difference between 8905 and its half, multiplied by 3, subtracted by the product of 8905 and its square?

To solve this problem, we first calculate the values: Double of 8905 = 8905 * 2 = 17810 Half of 8905 = 8905 / 2 = 4452.5 Square of 8905 = 8905 * 8905 = 79208025 Now, let's proceed with the calculation: Sum of 8905 and its double = 8905 + 17810 = 26715 Difference between 8905 and its half = 8905 - 4452.5 = 4452.5 Product of 8905 and its square = 8905 * 79208025 = 705116737625 Now, the expression becomes: sqrt((26715 + 17810) / 4452.5 * 3 - 705116737625) = sqrt(44525 / 4452.5 * 3 - 705116737625) = sqrt(9 - 705116737625) = sqrt(-705116737616) The square root of a negative number is undefined in real numbers. Hence, there is no real solution to this question.

Math question: What is the sum of all the digits in the number 8905?

To find the sum of the digits in the number 8905, we simply add 8 + 9 + 0 + 5. The sum is 22.

Find the product of the prime numbers obtained by adding a digit missing from the number 8905, when the missing digit can be any integer from 0-9.

To find the missing digit, we consider all the possible cases. By adding a digit, we have numbers 08905, 18905, ..., 98905. By checking the divisibility rules, we find that 2, 5, and 9457 are the prime factors for these numbers. Since we want the product of the prime factors, we multiply them: 2 * 5 * 9457 = 94,570. Therefore, the product is 94,570.
