What is the sum of the digits of the number 3885 when each digit is raised to the power of its position in the number?

To find the sum, we raise each digit to its position and add them up. The first digit, 3, is raised to the power of 1, giving us 3. The second digit, 8, is raised to the power of 2, giving us 64. The third digit, 8 again, is raised to the power of 3, equaling 512. Lastly, the fourth digit, 5, is raised to the power of 4, resulting in 625. Summing these values (3 + 64 + 512 + 625) gives us 1204 as the final answer.

Question: What is the value of 385^(2/3) times the square root of ((3885/15)^2 + 3885)?

To solve the given expression, we first calculate (3885/15)^2, which equals 1296. Then, adding 3885 results in 5181. Taking the square root of this gives us approximately 71.98. Next, we find the cube root of 385, which is approximately 7.494. Finally, multiplying 7.494 by 71.98 yields around 539.94. Therefore, the value of the expression 385^(2/3) times the square root of ((3885/15)^2 + 3885) is approximately 539.94.

What is the sum of the prime factors of 3885? And express the answer as a power of its least prime factor.

To find the prime factors of 3885, we prime factorize it as 3 × 5 × 7^2. The sum of these prime factors is 3 + 5 + 7 + 7 = 22. Expressing 22 as a power of its least prime factor, we have 2^1 × 11^1. Hence, the answer is 2^1 × 11^1.
