Math question: If you divide the number 4185 by 65 and then subtract the product of 81 and 23, what is the final result?

To solve this, first divide 4185 by 65, giving you 64. The product of 81 and 23 is 1863. Subtracting 1863 from 64 gives us -1799. So, the final result is -1799. In numerical form, it can be expressed as -1799 = 4185/65 - (81 * 23).

Math question: What is the largest prime factor of the number 4185?

To find the answer, we start by factoring 4185. First, we divide it by 3, and get 1395. Dividing 1395 by 3 again gives 465, then dividing 465 by 3 leaves 155. However, 155 is not divisible by 3. Next, we check for divisibility by 5, and find that 155 is divisible by 5, resulting in 31. As 31 is a prime number, it is the largest prime factor of 4185.

What is the sum of the digits when 4185 is expressed in exponential form?

In exponential form, 4185 can be written as 4 x 10³ + 1 x 10² + 8 x 10¹ + 5 x 10⁰. Adding the digits 4 + 1 + 8 + 5 results in a sum of 18.
