Math Question: What is the summation of the prime factors of 191 raised to the power of 3, subtracted by the square root of its largest prime factor?

To solve this question, we need to find the prime factors of 191, which is a prime number itself. The only prime factor is itself, so our summation is 191. Raising it to the power of 3 yields 7,309,681. The largest prime factor is 191 (since 191 is prime), and its square root is approximately 13.820. Subtracting the square root from the previous result, we get 7,309,681 - 13.820 = 7,309,667. Hence, the answer is 7,309,667.

Math question: What is the sum of the first ten prime numbers greater than 100?

To find the first ten prime numbers greater than 100, we start with 101, which is prime, and increment by 2 until we get 10 primes. These primes are 101, 103, 107, 109, 113, 127, 131, 137, 139, and 149. Adding them up, the sum is 1196.

Math Question: If the number 191 is multiplied by its factors excluding 1 and itself, and the product is increased by the reciprocal of its square root, what is the result?

Let's first determine the factors of 191: 1, 191. Multiplying the factors (excluding 1 and 191), we have 191 * 191 = 36481. Next, we find the square root of 191 (√191) ≈ 13.820. The reciprocal of the square root is approximately 1/13.820 ≈ 0.0723488. Adding the reciprocal of the square root to the product, 36481 + 0.0723488 ≈ 36481.0723488. Therefore, the result of multiplying the factors of 191 and adding the reciprocal of its square root is approximately 36481.0723488.
