Math question: How many times does the digit '8' appear in the number 6885?

To find the number of times '8' appears in 6885, we can analyze each digit of the number. Starting from the left, we have: - In the thousands place, there are no '8's. - In the hundreds place, there is one '8'. - In the tens place, there are no '8's. - In the units place, there is one '8'. Thus, the number 6885 has a total of 2 '8's.

What is the sum of the digits in 6885 multiplied by the difference between the first and last digit, divided by the second digit multiplied by the cube of the third digit, plus the fourth digit squared?

The sum of the digits in 6885 is 27. The difference between the first and last digit is (6-5) = 1. The second digit is 8, so the division is (27 * 1) / (8 * 8^3). The third digit is 8, so the cube is 8^3 = 512. Finally, the fourth digit is 5, so its square is 5^2 = 25. Plugging these values into the equation, we get (27 * 1) / (8 * 512) + 25 = 0.0038 + 25 = 25.0038. Therefore, the answer is 25.0038.

Math Question: What is the sum of the digits of the square root of 6885, when multiplied by the cube root of 6885, divided by the product of the prime factors of 6885?

To find the sum of the digits of the square root of 6885, we first calculate the square root, which is approximately 82.972. The sum of digits in 82.972 is 8+2+9+7+2 = 28. Next, we compute the cube root of 6885, which is approximately 19.796. Now, let's find the prime factors of 6885: 3 x 5 x 17 x 17. The product of the prime factors is 3 x 5 x 17 x 17 = 8670. Finally, by dividing the product of the prime factors (8670) into the product of the sum of digits of the square root (28) and the cube root (19.796), we have (28 x 19.796) / 8670 ≈ 0.6386. Therefore, the answer is approximately 0.6386.
