Math question: What is the product of 8161 multiplied by 3, divided by 7, added to the square root of 8161, subtracted by 15, raised to the power of 2?

Starting with 8161, let's follow the steps. First, multiply by 3 to get 24483. Next, divide by 7 to obtain approximately 3497.57. Then, add the square root of 8161 (approximately 90.3334) to yield approximately 3587.9034. Subtract 15 to obtain approximately 3572.9034. Finally, raise this value to the power of 2 to obtain approximately 12,763,563.0465. Hence, the answer is approximately 12,763,563.0465.

Math question: How many prime numbers can be formed by rearranging the digits of the number 8161?

To find the prime numbers formed by rearranging the digits of 8161, we need to consider the permutations of these digits. The number has 4 digits, so there are 4! = 24 possible permutations. Checking each permutation, we have 6 prime numbers: 8161, 8116, 6181, 6118, 8811, and 8611. These are the only prime numbers that can be formed by rearranging the digits of 8161.

What is the largest prime number less than 8161 that is divisible by 3?

The largest prime number less than 8161 is 8159. To find this, we start checking from 8161 and work our way backwards by subtracting 2 each time to stay in the prime number range. We notice that when we reach 8159, it is divisible by 3 because the sum of its digits (8 + 1 + 5 + 9 = 23) is divisible by 3. Therefore, 8159 is the largest prime number less than 8161 that is divisible by 3.
