Math question: If 6425 is multiplied by 7, then divided by the sum of its digits squared, what is the result?

To solve this question, we start by finding the sum of the digits: 6 + 4 + 2 + 5 = 17. We then square this value: 17^2 = 289. Next, we multiply 6425 by 7: 6425 * 7 = 44,975. Finally, we divide 44,975 by 289: 44,975 / 289 ≈ 155.41 (rounded to two decimal places). Therefore, the result is approximately 155.41.

Question: What is the largest prime number that can be formed by rearranging the digits of the number 6425?

To find the largest prime number, we can start by observing that the given number is not divisible by 2 or 5. Thus, any rearrangement ending in 2 or 5 cannot be prime. Let's consider the possibilities: 6425, 6452, 6524, 6542, 6245, 6254, 6245, 6254, 6425, 6452, 6524, 6542. Testing them for primality, 6524 = 2 x 2 x 17 x 19 and 6542 = 2 x 7 x 467. Therefore, the largest prime rearrangement is 6425, as none of the others are prime.

If the number 6425 is multiplied by 3 and then divided by 5, subtracted from the sum of 468 and 1855, and finally squared, what is the resulting value?

First, multiply 6425 by 3, yielding 19275. Then divide this by 5, giving 3855. Next, find the sum of 468 and 1855, which is 2323. Subtract 3855 from 2323, resulting in -1532. Finally, square -1532 to get 2345024. Therefore, the resulting value is 2345024.
