Changing the sign of an Exponent

If a term in the numerator is moved to the 

denominator the exponent will now have the

opposite sign.  (If the exponent was negative

it will become positive and vice versa.)

The same is true if a term in the denominator

is moved to the numerator the exponent will 

now have the opposite sign.
