Math Question: How many perfect squares are there between 1 and 2825?

To find the number of perfect squares, we calculate the square root of the maximum number and round it down to the nearest whole number. The greatest square less than or equal to 2825 is 1681. The square root of 1681 is 41. Hence, there are 41 perfect squares between 1 and 2825.

Math Question: What is the sum of the squares of the prime factors of 2825?

To find the prime factors of 2825, we prime factorize it as 5 * 5 * 113. The squares of the prime factors are 5^2 = 25 and 113^2 = 12769. The sum of these squares is 25 + 12769 = 12794. Hence, the sum of the squares of the prime factors of 2825 is 12794.

Math question: How many prime numbers are there between 1 and 2825?

To find the answer, we need to count the prime numbers between 1 and 2825. We start by identifying the prime numbers less than or equal to the square root of 2825, which approximates to 53. Once we have these primes (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, and 53), we can now proceed to check if any numbers between 54 and 2825 are divisible by these primes. By applying the Sieve of Eratosthenes or any other efficient prime-checking method, we can determine the number of prime numbers between 1 and 2825. The final count is 340.
