Math question: Find the sum of the prime factors of the number 7910.

To find the prime factors of 7910, we divide it by prime numbers starting from 2. Prime factors include 2, 5, and 397. Thus, 2 + 5 + 397 = 404 is the sum of the prime factors of 7910.

Math question: What is the positive square root of the sum of the first three prime numbers multiplied by the square root of the highest three-digit number plus the cube root of 7910?

The first three prime numbers are 2, 3, and 5. The sum of these numbers is 2 + 3 + 5 = 10. The highest three-digit number is 999, whose square root is approximately 31.62. The cube root of 7910 is approximately 19.68. Thus, the expression becomes √(10) * √(999) + ∛(7910). Evaluating this, we get √10 * √999 + ∛7910 ≈ 3.162 * 31.62 + 19.68 ≈ 99.85 + 19.68 ≈ 119.53. Therefore, the answer is approximately 119.53.

Math question: If a number is increased by 50% and then decreased by 30%, what is the result?

To find the result, we start with the number 7910. Increasing it by 50% gives us 7910 + (50/100) * 7910 = 7910 + 3955 = 11865. Now, decreasing it by 30%, we have 11865 - (30/100) * 11865 = 11865 - 3559.5 = 8305.5. Therefore, the final result after the two operations is 8305.5.
