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