The major advantage of exponential notation is that it simplifies a number into a more readable form, so we don't have to count all the zeros every time we look at it / calculate it. It helps us to identify big numbers as small decimals which we are more familiar with.
Assuming I see a force F acting on an object at an angle theta with the horizontal pushing it through a rough surface over a distance L such that the horizontal component is just required to overcome friction.
Then work done is
W=FLcos(theta)
(Read assumptions above due to lack of diagram)
