Math question: How many prime numbers are there between 511 and 1,000 (inclusive)?

To solve this, we observe that the prime numbers up to √1,000 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31. Since a prime number cannot have any factors other than 1 and itself, we only need to check divisibility by prime numbers up to √1,000. Starting with 511, we find that 511 = 7 × 73. Thus, the prime numbers between 511 and 1,000 are 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, and 997. Therefore, there are a total of 63 prime numbers between 511 and 1,000.

Question: What is the sum of the prime factors of the number 511, excluding 1, up to 200 characters long?

To find the prime factors of 511, we divide it by prime numbers starting from 2. The prime factors of 511 are 7 and 73. Adding these prime factors together, we get 7 + 73 = 80.

Math question: What is the value of 511 divided by 13, squared, minus 3 times the square root of 511?

To find the answer, we first divide 511 by 13, which gives us approximately 39.307. Squaring this value results in approximately 1543.55. Next, we calculate the square root of 511, which is approximately 22.625. Multiplying it by 3 gives us approximately 67.875. Now, subtracting 67.875 from 1543.55, we get approximately 1475.675. Hence, the answer is approximately 1475.675.
