#5.4 xx 10^-5#

Explanation:

Scientific notation is a way to use rename really large, or really small numbers so that they are easier to use.

Your number is really small:

#0color(red)"."0000color(red)"5"4#
#color(white)"x"=>#

We are going to move the decimal place to the right to remove all of the #0's#. Put your finger at the decimal place and move it all the way until the 5. You should have moved #5# spaces.

Put the decimal there and you should have:
#5.4#

Now since we moved #"5 spaces to the right"# we are going to add a negative exponent to ten:
#5.4 xx 10^-5#
