Question: If the number 1145 is multiplied by the sum of its digits, what is the resulting product?

To calculate the product, we need to find the sum of the digits in 1145, which is 1 + 1 + 4 + 5 = 11. Then, we multiply this sum by the original number: 11 * 1145 = 12595. Therefore, the resulting product of multiplying the sum of the digits of 1145 is 12595.

What is the product of 1145 when multiplied by 5 and divided by 2, subtracted from the sum of 1145 divided by 4 and squared?

The product of 1145 and 5 is 5725. So, 5725 divided by 2 is 2862.5. The sum of 1145 divided by 4 is 286.25. When squared, it becomes 82090.15625. Finally, subtracting 2862.5 from 82090.15625 yields the answer of 79227.65625.

Math Question: What is the sum of the last three digits of the product of 1145 and the square root of 1145?

To find the product of 1145 and the square root of 1145, we first calculate the square root of 1145, which is approximately 33.853. Then, we multiply this by 1145, yielding approximately 38647.725. Now, focusing on the last three digits of this number, which are 647, we want to sum these digits. Hence, we have 6 + 4 + 7 = 17. Therefore, the sum of the last three digits of the product of 1145 and the square root of 1145 is 17.
