Math question: What is the sum of all the prime numbers between 1982 and 2000 (inclusive)?

To find the solution, we need to identify the prime numbers between 1982 and 2000. The prime numbers in this range are 1987, 1993, and 1997. Now, let's calculate their sum: 1987 + 1993 + 1997 = 5977 Therefore, the sum of all the prime numbers between 1982 and 2000 is 5977.

Math question: What is the product of 1982 multiplied by the sum of its digits, divided by the difference between its digits and the cube root of 200?

To find the product of 1982 and the sum of its digits, we first sum the digits: 1 + 9 + 8 + 2 = 20. Next, we calculate the difference between the digits: 9 - 1 = 8. Now, let's calculate the cube root of 200 which is approximately 5.848. Finally, the product of 1982 multiplied by the sum of its digits is 1982*20 = 39640. Dividing this by the difference between the digits and the cube root of 200, we have: 39640 / (8 - 5.848) = 39640 / 2.152 ≈ 18416. Therefore, the answer is approximately 18416.

Math question: What is the product of the last two prime numbers less than 1982?

To find the last two prime numbers less than 1982, we start by listing prime numbers in descending order: 1982, 1981, 1979, 1973, 1973 is the last prime number below 1982. The product of 1979 and 1973 is 3,910,267. There are still 329 characters remaining. If you need further explanation or have any other questions, feel free to ask!
