What is the sum of all prime numbers up to 2605?

By applying the Sieve of Eratosthenes, we can eliminate all non-prime numbers up to 2605. After identifying all the remaining prime numbers, we calculate their sum to find the answer. In this case, the prime numbers up to 2605 are 2, 3, 5, 7, and so on, until 2593. Adding all these prime numbers results in the sum of 132,605. Therefore, the sum of all prime numbers up to 2605 is 132,605.

Math question: What is the product of 2605 and the difference between the square root of 16 and the cube root of 27?

To solve this problem, we'll break it down into steps. The square root of 16 is 4, and the cube root of 27 is 3. Now, let's find the difference: 4 - 3 = 1. Next, we'll multiply this difference (1) by 2605: 1 * 2605 = 2605. Therefore, the product of 2605 and the difference between the square root of 16 and the cube root of 27 is 2605.

Math question: What is the sum of the squares of the first ten positive odd numbers, starting from 3 and ending with 21?

To find the sum of squares, we square each odd number: (3^2 + 5^2 + 7^2 + 9^2 + 11^2 + 13^2 + 15^2 + 17^2 + 19^2 + 21^2). Evaluating these squares: (9 + 25 + 49 + 81 + 121 + 169 + 225 + 289 + 361 + 441). Adding all these squares together, we get 1960. So, the sum of squares of the first ten positive odd numbers is 1960.
