To understand how to do this, let's first "unmultiply":
Look at the above. If you multiplied them, wouldn't you get the original fraction? Writing the expression as two separate fractions like this makes it clear what to do. For the first fraction we simply divide 1.83 by 1.2. For the second fraction we will use the rule for exponents that tells us that when dividing you subtract the exponents:
or
which is in scientific notation. SO this is our simplified expression.
