Step-by-step explanation: Simplify expressions with negative exponents

The Quotient Property of Exponents, introduced in Divide Monomials, had two forms depending on whether the exponent in the numerator or denominator was larger.

QUOTIENT PROPERTY OF EXPONENTS

If  

a

is a real number,  

a

≠

0

, and  

m

,

n

are whole numbers, then

What if we just subtract exponents, regardless of which is larger? Let’s consider  

x

x

5

.

We subtract the exponent in the denominator from the exponent in the numerator.
