[tex]( \frac{ \sqrt{3} }{2} ) {}^{5} \times ( \frac{2}{ \sqrt{3} } ) {}^{ - 2} \\ = \frac{ \sqrt{3 }^{5} }{2 {}^{5} } \times \frac{ \sqrt{3 {}^{2} } }{2 {}^{2} } = \frac{3 \times 3 \times \sqrt{3} }{32} \times \frac{3}{4} \\ = \frac{9 \sqrt{3} }{32} \times \frac{3}{4} \\ = \frac{27 \sqrt{3} }{128} [/tex]
