Math question: If we express the number 2185 as the sum of its digits multiplied by their respective place values, what is the result?

To find the sum of the digits multiplied by their place values, we break down 2185 into 2000 + 100 + 80 + 5. Then we calculate (2 × 2000) + (1 × 100) + (8 × 10) + (5 × 1) = 4000 + 100 + 80 + 5 = 4185. Therefore, the result is 4185.

Math question: What is the largest prime factor of the number 2185?

To find the largest prime factor of 2185, we first factorize it using a trial division method. We divide 2185 by 2, and it doesn't evenly divide. Next, we try 3, which divides 2185 with a quotient of 728 and a remainder of 1. Continuing our division, we try 5, which goes into 728 with a quotient of 145. Finally, we divide 145 by 5, which gives a quotient of 29. Therefore, 29 is the largest prime factor of 2185.

Math question: What is the sum of the digits in the number 2185 raised to the power of 3, divided by the square root of its reverse?

To find the answer, we first calculate the reverse of 2185, which is 5812. Taking the square root of 5812, we get approximately 76.284. Now, raising 2185 to the power of 3 results in 103,020,421,025. The sum of the digits in this number is 0+1+0+2+0+4+2+1+0+2+5, which equals 17. Finally, dividing 103,020,421,025 by 76.284 gives us approximately 1,352,849,523. Considering the initial question, the sum of the digits in this final answer is 1+3+5+2+8+4+9+5+2+3, amounting to 43.
