Math Question: What is 7837 divided by the sum of its digits squared, added to the difference between the largest and smallest digit in the number, then multiplied by the square root of the number itself?

To solve this, we first need to find the sum of the digits, which is 7 + 8 + 3 + 7 = 25. Squaring this gives us 625. The largest digit is 8, and the smallest digit is 3, so their difference is 5. The square root of 7837 is approximately 88.52. Plugging in these values, we have (7837 ÷ 625) + 5) × 88.52. Simplifying further, (12.5792 + 5) × 88.52 = 17.5792 × 88.52 = 1553.053344. Therefore, when following the given mathematical operations, the answer is approximately 1553.053344.

What is the result when you divide the square of the sum of the digits of 7837 by the product of the digits multiplied by the sum of the digits?

Let's break it down. The sum of the digits is 7 + 8 + 3 + 7 = 25. The product of the digits is 7 × 8 × 3 × 7 = 1176. The square of the sum is 25² = 625. Now, dividing 625 by 1176 yields approximately 0.5312 (rounded to four decimal places). So, the answer is 0.5312.

Question: What is the smallest prime number greater than 7837 that is also divisible by 7 and has 3 as the sum of its digits?

The smallest prime number greater than 7837 that is divisible by 7 and has a digit sum of 3 is 7903. To verify, 7903 is a prime number (divisible only by 1 and itself), it is divisible by 7 as 7903 ÷ 7 = 1129, and the sum of its digits is 7 + 9 + 0 + 3 = 19, which reduces to 1 + 9 = 10, then 1 + 0 = 1. Hence, 7903 satisfies all the given conditions.
