Seja \text{A}=\left(\dfrac{1}{\text{x}}\right)^3+\left(\dfrac{1}{\text{x}}\right)^2

 

Desta maneira, temos:

 

\text{A}=\dfrac{1}{\text{x}^3}+\dfrac{1}{\text{x}^2}

 

Donde, obtemos:

 

\text{A}=\dfrac{\text{x}^2+\text{x}^3}{\text{x}^2\cdot\text{x}^3}

 

\text{A}=\dfrac{\text{x}^2\cdot(1+\text{x})}{\text{x}^5}
