Question: What is the sum of all the digits in the number 4249?

To find the sum of the digits in the number 4249, we add 4 + 2 + 4 + 9, which gives us a total of 19.

Math question: Why is 4249 a prime number?

To prove that 4249 is prime, we need to determine if it has any divisors other than 1 and itself. We can find this by checking all possible divisors up to the square root of 4249, i.e., 65.17 (rounded to 65). After examining integers from 2 to 65, none evenly divide 4249, making it a prime number. This means that 4249 cannot be expressed as a product of two smaller positive integers. Prime numbers have significant applications in cryptography, number theory, and other areas of mathematics.

Math question: What is the smallest prime number greater than 4249 which, when multiplied by 2, then subtracted by 21, gives a perfect square?

To find the answer, we start by determining the smallest prime number greater than 4249. By listing primes consecutively, we find that 4253 is the first prime greater than 4249. Next, we multiply 4253 by 2, which gives us 8506. Subtracting 21 from this product, we obtain 8485. Now, we need to check if 8485 is a perfect square. Taking the square root of 8485, we get approximately 92.087, which is not an integer. Therefore, 8485 is not a perfect square. Continuing to check larger primes, we find that 4259 is the next prime number. Repeating the above process, we have 4259 * 2 - 21 = 8507 - 21 = 8486. Upon checking whether 8486 is a perfect square, we observe that its square root is approximately 92.124. Again, this is not an integer. Therefore, we continue this process until we find the first prime number which, when multiplied by 2 and subtracted by 21, results in a perfect square.
