Math question: What is the sum of 8581 and its double?

To find the sum of 8581 and its double, we multiply 8581 by 2, which equals 17162. Then, we add this result to 8581, obtaining 25743.

Math question: What is the largest prime factor of the number 8581?

To find the largest prime factor of a number, we start by dividing it by the smallest prime number, which is 2. However, since 8581 is an odd number, it is not divisible by 2. Now, we move on to the next prime number, 3. Performing the division, we get 8581 ÷ 3 = 2860.333 (not a whole number), indicating that 3 is not a factor. Continuing this process, we divide by 5, 7, 11, and 13, but none of them yield a whole number quotient. However, when we divide 8581 by 17, we obtain 8581 ÷ 17 = 505 with no remainder, implying that 17 is a prime factor. Further division leads to 505 ÷ 17 = 29, which is a prime number itself. Thus, the largest prime factor of 8581 is 17. Note: The factorization of 8581 = 17 × 29.

What is the value of the expression (3^6) + (2^3) - (5^2) + (8^4) - (1^5)?

The expression simplifies to 729 + 8 - 25 + 4096 - 1 = 4807.
