One hundred thousand multiple eight point one billion divided by one thousand

To solve this problem, we need to multiply 100,000 by 8.1 billion and then divide the result by 1,000.

First, we'll multiply 100,000 by 8.1 billion:

100,000 * 8,100,000,000 = 810,000,000,000,000

Next, we'll divide the result by 1,000:

810,000,000,000,000 / 1,000 = 810,000,000,000

Therefore, 100,000 multiplied by 8.1 billion and then divided by 1,000 is equal to 810 billion.
