Math question: What is the product of 997 squared divided by 3, multiplied by the square root of 8, and then subtracted by the sum of 997 and 3?

To solve this, we begin by squaring 997, resulting in 994009. Dividing by 3 gives us 331336.33 recurring. Next, we find the square root of 8, which is approximately 2.8284. Multiplying 331336.33 recurring by 2.8284 yields 935018.3974 recurring. Now we add 997 to 3, which gives us 1000. Finally, we subtract 1000 from 935018.3974 recurring to obtain the answer of 934018.3974 recurring. Thus, the result is 934018.40 (rounded to two decimal places).

Math question: What is the sum of all three-digit numbers that are multiples of 997?

To find the sum of all three-digit multiples of 997, we first need to determine the lower and upper limits. The closest multiple of 997 below 100 is 997 itself, while the closest multiple above 999 is 1994. Next, we find the number of terms in this arithmetic sequence using the formula: number of terms = (last term - first term) / common difference + 1 Thus, we get (1994 - 997) / 997 + 1 = 2 + 1 = 3 terms. Now, we calculate the sum using the formula for the sum of an arithmetic sequence: sum = (number of terms / 2) * (first term + last term) Plugging in the values, we have (3 / 2) * (997 + 1994) = 1.5 * 2991 = 4486.5. Therefore, the sum of all three-digit multiples of 997 is 4486.5.
