3. copyright©amberpasillas2010 How do you divide expressions with exponents ? Ex: a5a5 a3a3 Let’s look at each problem in factored form. a a a a a a a a x x Notice that you can cancel from numerator to denominator. = a 2 = x2= x2 Do you see a “ shortcut ” for dividing these expressions? =

4. copyright©amberpasillas2010 Just Subtract the Exponents! Your short cut is called the Quotient of Powers Property.

5. copyright©amberpasillas2010 Simplify. x 5 x 2 == x 5 x 2 = Quotient of Powers Property x a x b = or “When you divide powers, you subtract the exponents!”
