Question: What is the result of multiplying 3887 by its square root, dividing by the sum of its digits, and then subtracting the cube root of 3887?

Let's break down the calculation step by step. Firstly, finding the square root of 3887, we get approximately 62.37. Next, adding its digits, 3 + 8 + 8 + 7, gives us 26. Now, dividing 3887 by 26, we obtain approximately 149.50. Finally, finding the cube root of 3887, we get approximately 15.23. Substituting these values, we have (3887 * 62.37) / 26 - 15.23. After evaluating this expression, the answer is approximately 9391.82. Explanation: This combination of operations introduces various concepts in mathematics, including multiplication, square roots, addition, division, cube roots, and subtraction. It showcases the interplay between these operations and allows for an application of mathematical principles on a specific number, 3887, demonstrating the versatility of mathematics in problem-solving.

Question: What is the sum of the prime numbers less than 3887 and the number of even multiples of 7 greater than 3887?

To solve this, we first find the prime numbers less than 3887: 2, 3, 5, 7,... By applying the Sieve of Eratosthenes, we determine that the prime numbers less than 3887 are {2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, ...}. The total number of prime numbers less than 3887 is 456. Now, let's determine the number of even multiples of 7 greater than 3887. Since the first even multiple of 7 greater than 3887 is 3890, we can write the sequence as {3890, 3904, 3918, ...}. By dividing 3887 by 7, we obtain 555 (rounded down since we're looking for multiples greater than 3887). So, the number of even multiples of 7 greater than 3887 is 555. Finally, we find the sum of these two values: 456 + 555 = 1011. Hence, the answer is 1011.

Math question: Find the sum of the digits of the number 3887 when each digit is raised to the power of its corresponding place value, starting from the right (ones, tens, hundreds, and thousands).

To solve this problem, we need to calculate (7^0) + (8^1) + (8^2) + (3^3). Evaluating each term gives us 1 + 8 + 64 + 27, thus the sum is 100. The sum of the digits in the number 3887, with each digit raised to its corresponding place value, is 100.
