Math question: What is the sum of the prime factors of the number 2528?

To find the prime factors of 2528, we start by dividing it by the smallest prime number, 2. Continuing until we can no longer divide by 2, we obtain factors 2 * 2 * 2 * 7 * 11. Therefore, the prime factors of 2528 are 2, 2, 2, 7, and 11. Adding them up, 2 + 2 + 2 + 7 + 11 = 24. Hence, the sum of the prime factors of 2528 is 24.

Math question: How many different ways can the number 2528 be arranged?

To find the number of different ways to arrange the number 2528, we have to consider the number of unique permutations. The first step is to determine the number of times each digit appears. In this case, there are two 2's, one 5, and one 8. Therefore, the number of unique permutations is given by the formula: P = 4! / (2! * 1! * 1!) = 4 * 3 * 2 * 1 / (2 * 1 * 1) = 12. Hence, there are 12 different ways the number 2528 can be arranged.

Question: What is the square root of the sum of the prime factors of 2528, subtracted by the difference between the number of divisors and the number of multiples of 6 within the range of the first 100 positive integers?

First, let's factorize 2528: 2^4 * 7 * 9. The prime factors are 2 and 7. The square root of the sum of these prime factors (2 + 7 = 9) is 3. Now, let's find the divisors and multiples of 6 within the range of the first 100 positive integers: - Divisors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96. (Total: 12) - Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96. (Total: 16) The difference between the number of divisors and multiples of 6 is 12 - 16 = -4. Therefore, the answer is 3 - (-4) = 7. The final answer is 7.
