Answer:

#8.1 xx 10^5#

Explanation:

Count the number of times you need to shift the number to the right before it's less than #10#. This gives you the exponent.

If you started with a number less than #1# then count the number of times you need to shift it to the left before it's greater than or equal to #1#.

For example, #0.0023 = 2.3 xx 10^(-3)#
