Math question: What is the sum of the digits in the number 4005?

To find the sum of the digits in 4005, we add each individual digit: 4 + 0 + 0 + 5 = 9. So, the sum of the digits in 4005 is 9.

Math Question: What is the sum of the digits in the number 4005 multiplied by the square root of 4005, divided by 3 and then subtracted by the cube of 4005?

To find the sum of the digits in 4005, we add: 4 + 0 + 0 + 5 = 9. Now, multiplying 9 by the square root of 4005 (which is approximately 63.20), we get 9 * 63.20 = 568.80. Dividing this by 3 gives us approximately 189.60. Finally, subtracting the cube of 4005 from 189.60, we have 189.60 - (4005 * 4005 * 4005) ≈ -243,581,193,592,512,895,175. Therefore, the answer is approximately -243,581,193,592,512,895,175.

Math question: What is the sum of all the even numbers from 1 to 4005, inclusive?

To find the sum of even numbers, we need to calculate the arithmetic mean of the first even number, which is 2, and the last even number, which is 4004. The formula for the sum of an arithmetic progression is: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, the number of terms is (4004-2)/2 + 1 = 2002. Therefore, the sum of even numbers from 1 to 4005 is Sn = (2002/2)(2 + 4004) = 2002(4006) = 8,025,212.
