Answer:

#9.105xx10^2#

Explanation:

Keep the decimal point where it is but slide the number to the right 2 places giving:

#9.105#

But this is a different value so we need to add a mathematical correction.

If we have: #9.105 xx 100# then this corrects the intrinsic value.

Now we change the format to:

#9.105xx10^2# Which is what you are after:

You must end up with only 1 digit to the left of the decimal point for it to be in scientific notation

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Further example
Suppose we had: #0.09105#

Then this would be #(9.105)/(100)#

Which ends up as: #9.105xx10^(-1)#
