+427 If you just want the answer, that is 8.7 * 10-4
So you know in future, if you want to change numerical to standard form like this, click the "=" key again.
If you want to know how to do scientific notation yourself:
consider the first significant number (non-zero) as the starting point. Now you want to see how many digits away is that from it's normal position (i.e. 8.0). In this case, it's gone down 4 digits, this means it will be 10-4. If it went up to say 870000.0, you can see "8" moved up 5 digits, making that 8.7 * 105.
