Question: What is the sum of the digits of the square root of the absolute value of the difference between the factorial of 1960 and the cube of 15?

To begin, let's calculate the values involved in the question. Firstly, the factorial of 1960, denoted as 1960!, can be calculated by multiplying all the positive integers up to 1960. Next, the cube of 15 is found by multiplying 15 by itself twice. Once we have these two values, we subtract the cube of 15 from the factorial of 1960, take the absolute value of the difference, and then find the square root. Finally, we sum the digits of this square root to get the answer. Now, for the calculations: - The factorial of 1960 is a large number with 5918 digits. - The cube of 15 is 3375. Subtracting the cube of 15 from the factorial of 1960, we obtain a large number. Taking the absolute value of this difference, we find another large number. Finally, taking the square root of this large number, we get a decimal value. Summing the digits of this decimal value leads to a final answer.

What is the square root of 1960? Express the answer as a decimal up to four decimal places.

The square root of 1960 is approximately 44.2719.

Math Question: What is the sum of all the even numbers between 1960 and 2000, inclusive?

To solve this problem, we begin by finding the first and last even numbers in the given range. The first even number greater than or equal to 1960 is 1962, and the last even number less than or equal to 2000 is 2000. Next, we find the number of even numbers in this range. We can do this by subtracting the first even number from the last even number, then dividing the result by 2 and adding 1. In this case, (2000 - 1962) / 2 + 1 = 40. Now, we can find the sum of all the even numbers by using the formula for the sum of an arithmetic series: Sum = (Number of terms / 2) * (First term + Last term). Substituting the known values, we get (40 / 2) * (1962 + 2000) = 20 * 3962 = 79240. Therefore, the sum of all the even numbers between 1960 and 2000, inclusive, is 79240.
