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.

Move only the terms in the numerator to the denominator. Keep in mind the only thing that should change is the exponent will now have the opposite sign.
Now move the terms that were originally in the denominator to the numerator. Keep in mind the only thing that shouldchange is the exponent will now have the opposite sign.

EXAMPLE 7Rewrite the expression with only positive exponents :
Rewrite the expression so that every term has an exponent.
Move any term to the denominator that has a negative exponent
in the numerator.
we only move a term if the exponent is negative, Notice that the –5 did not move to the denominator,
not the number itself.

EXAMPLE 10
Move any term to the denominator that has a negative exponent in the numerator.
Rewrite the expression with only positive exponents :
Whenever the numerator does not have a value place a 1 in the numerator.
Notice that only the exponent has an opposite sign, the –2 has the same sign.

the same nonzero base, ADD the exponents. Use
this sum as the exponent of the common base.

Quotient Rule with
When dividing exponential expressions with
the same nonzero base, SUBTRACT the
exponent in the numerator minus the exponent
in the denominator. Use the difference as the
exponent of the common base.
