Answer:
91000 or 9.100 * 10^4
Explanation:
This mean that a lot of things are going to change. The decimal will disappear. If that happens what you have is
90998
Now many other things will disappear as well because you are rounding
The easiest way to show this is just to round which will give you
91000
If you know scientific notation then the answer becomes
9.100 * 10^4
