Question: What is the sum of the squares of the prime factors of 791?

To find the answer, we first need to find the prime factors of 791. The prime factorization of 791 is 7 * 113. Now, let's square each prime factor: (7^2) + (113^2) = 49 + 12769 = 12818. Therefore, the sum of the squares of the prime factors of 791 is 12818.

What is the product of the square root of 791 multiplied by the sum of its digits, divided by the difference between the greatest prime factor of 791 and the least prime factor, squared?

The square root of 791 is approximately 28.09, and the sum of its digits is 17. The greatest prime factor of 791 is 17, and the least prime factor is 7. So, the difference between them is 10. Thus, the product is (28.09 * 17) / (10^2) = 47.68 / 100 = 0.4768.

Math question: What is the result of dividing 791 by the sum of its digits multiplied by the square root of its units digit, rounded to the nearest whole number?

The sum of the digits in 791 is 7 + 9 + 1 = 17. The square root of the units digit (1) is 1. When multiplied together, we get 17 * 1 = 17. So, dividing 791 by 17 gives us approximately 46.5. Since we were asked to round to the nearest whole number, the answer is 47.
