Answer:

I got #9xx10^-10#

Explanation:

You must move the point to the right counting how many positions you moved up to passing the first non-zero digit (#9#):
Here you move the point of #10# positions.
You then have:
#9xx10^-10#
Where the right movement is represented by the minus sign and the number of positions by the numerical coefficient of #10#.
