I think I am at extended abstract because I am creating something that shows others how to convert standard to ordinary form and vice versa.
To solve this:
First, you take 8.7x10 to the third power.
All you have to do, is move the decimal in 8.7 over three places.
8.7x10 to the third power= 8700
Now all you have to do is choose the right sign.
The answer is:
> because 8700 is bigger than 6870
