[tex] \frac{ {( - 2a)}^{3} {(2a)}^{ - \frac{2}{3} } }{ {( {16}^{4}) }^{ \frac{1}{3} } } \\ = \frac{ { - 2}^{3} \times {a}^{3} \times {2}^{ - \frac{2}{3} } \times {a}^{ - \frac{2}{3} } }{ {2}^{ \frac{16}{3} } } \\ = - 8 \times {a}^{ \frac{7}{3} } \times {2}^{ \frac{ - 18}{3} } \\ = - 8 \times {2}^ { - 6} \times {a}^{ \frac{7}{3} } \\ = \frac{ - 8}{64} \times {a}^{ \frac{7}{3} } \\ = - \frac{1}{8} \times {a}^{ \frac{7}{3} } [/tex]
