Question: What is the sum of the digits in the number 3155, multiplied by the number of factors of 3155 plus the square root of 3155 minus the number of prime factors of 3155, all divided by the product of the prime factors of 3155?

The sum of the digits in the number 3155 is 3 + 1 + 5 + 5 = 14. The number of factors of 3155 can be found by prime factorizing it as 5 * 631. Hence, there are (1 + 1) * (1 + 1) = 4 factors. The square root of 3155 is approximately 56.13. The number 3155 only has one prime factor, which is 5. Therefore, plugging these values into the equation yields: (14 * 4) + 56.13 - 1 / 5 = 56.7 + 56.13 - 0.2 = 112.93. Thus, the answer is 112.93.

Math Question: What is the square root of the sum of the cubes of the prime factors of 3155?

To find the prime factors of 3155, we factorize it into 5 x 631. Taking the cube of each prime factor, we get 5³ + 631³ = 125 + 251,031. Adding these cubes gives us 251,156. Now, to find the square root, we take √251,156, which simplifies to approximately 501.15. Therefore, the square root of the sum of the cubes of the prime factors of 3155 is around 501.15.

Math question: What is the sum of the digits of the product of 3155 and the square root of 3155?

To calculate the sum of the digits, we start by finding the square root of 3155, which is approximately 56.133. Next, we multiply this value by 3155, which yields 177,289.615. Summing up the digits in 177,289.615 (ignoring the decimal part), we get 1 + 7 + 7 + 2 + 8 + 9 + 6 + 1 + 5 = 46.
