What is the sum of the digits of the number 9645 when multiplied by 3 and divided by the product of the first two prime numbers?

To find the sum of the digits of 9645, we multiply it by 3, resulting in 28935. The product of the first two prime numbers, 2 and 3, is 6. Dividing 28935 by 6 gives a quotient of 4822.5. Therefore, the sum of the digits of 9645, when multiplied by 3 and divided by the product of the first two prime numbers, is 4822.5.

Question: What is the largest three-digit multiple of 25 that is less than 9645?

To find the largest three-digit multiple of 25, we divide 9645 by 25 which equals 385.8. Since we need the largest multiple less than 9645, we round down the decimal part and get 385. Finally, we multiply 25 by 385, giving us 9625, which is the largest three-digit multiple of 25 less than 9645.

What is the sum of the digits in the number 9645 multiplied by 3, divided by 5, subtracted by 150, and squared?

To find the sum of the digits in 9645, we add 9 + 6 + 4 + 5, which gives us 24. When we multiply 24 by 3, we get 72. Dividing 72 by 5 equals 14.4. Subtracting 150 from 14.4 results in -135.6. Finally, squaring -135.6 gives us 18,423.36. Therefore, the answer is 18,423.36.
