Answer 1

Well, try to figure it out on your own. Look at the answer choices and ask yourself, "Is there any way that 10 to the power of *blank* can get to this answer?"
For example: The first one - 10^-3. Is there any way 10 can get to 10^-3. This one's easy. Yes, of course. By adding the power of -3.
Now you try it.
Hope this helps. :)
