[tex] = ({125})^{ - \frac{ 2}{3} } - ( {100})^{ - \frac{3}{2} } \\ = \frac{1}{ {125}^{ \frac{2}{3} } } - \frac{1}{ {100}^{ \frac{3}{2} } } \\ = \frac{1}{ \sqrt[3]{ {125}^{2} } } - \frac{1}{ \sqrt[2]{ {100}^{3} } } \\ = \frac{1}{25} - \frac{1}{1000} \\ = \frac{40 - 1}{1000} \\ = \frac{39}{1000} [/tex]
