Math question: What is the sum of the digits in the number 7858 when multiplied by 3, squared, divided by 2, and finally subtracted from the original number?

To find the sum of the digits in 7858, we add 7 + 8 + 5 + 8 = 28. Multiplying this sum by 3, we get 28 * 3 = 84. Squaring this result, we have 84^2 = 7056. Dividing 7056 by 2 yields 3528. Finally, subtracting 3528 from the original number 7858, we get 4330. Therefore, when we go through the given steps, the final answer is 4330.

Math Question: What is the largest prime factor of the number 7858?

To find the largest prime factor of 7858, we need to factorize the number. Dividing 7858 by the smallest prime numbers (starting from 2), we find that 7858 = 2 * 3929. Since 3929 is not divisible by any prime numbers smaller than itself, it must be prime. Therefore, the largest prime factor of 7858 is 3929.

Math question: What is the sum of the square root of 7858 multiplied by the cube root of 7858, divided by the logarithm of 7858?

To find the answer, we first calculate the square root of 7858, which is approximately 88.576. Then, we calculate the cube root of 7858, which is approximately 19.501. Next, we calculate the logarithm of 7858 to the base 10, which is approximately 3.895. Now, multiplying 88.576 by 19.501 gives us approximately 1722.339. Finally, dividing 1722.339 by 3.895 gives us approximately 442.627. Therefore, the answer is approximately 442.627.
