Observe que:

 

16^{-1}=\dfrac{1}{16}

 

2^{-5}=\left(\dfrac{1}{2}\right)^5=\dfrac{1}{32}

 

5^{-1}=\dfrac{1}{5}

 

Logo, podemos afirmar que:

 

\text{X}=16^{-1}\div2^{-5}\cdot5^{-1}=\dfrac{1}{16}\div\dfrac{1}{32}\cdot\dfrac{1}{5}

 

\text{X}=\dfrac{32}{16}\cdot\dfrac{1}{5}

 

\text{X}=2\cdot\dfrac{1}{5}

 

\text{X}=\dfrac{2}{5}
