inverse property of multiplication

#### Work Step by Step

RECALL: The inverse property of multiplication states that for any nonzero real number $a$, $a \cdot \dfrac{1}{a} = 1$ Note that when $a= \dfrac{2+m}{2-m}$, then $\dfrac{1}{a} = \dfrac{2-m}{2+m}$ Thus, the given statement illustrates inverse property of multiplication.
