[tex] {(1 \frac{1}{3}) }^{8} \div ({1 \frac{7}{9} ) }^{3} - ( {1 \frac{1}{3} })^{9} \times ( - { \frac{27}{64} )}^{3} = {( \frac{4}{3} )}^{8} \div {( \frac{16}{9}) }^{3} - {( \frac{4}{3} )}^{9} \times ( - \frac{27}{64} {)}^{3} = \frac{ {4}^{8} }{ {3}^{8} } \times \frac{ {( {3}^{2} )}^{3} }{ ({ {4}^{2}) }^{3} } - \frac{ {4}^{9} }{ {3}^{9} } \times ( - \frac{ { ({3}^{3}) }^{3} }{ ({ {4}^{3}) }^{3} } ) = \frac{ {4}^{8} }{ {3}^{8} } \times \frac{ {3}^{6} }{ {4}^{6} } - \frac{ {4}^{9} }{ {3}^{9} } \times ( - \frac{ {3}^{9} }{ {4}^{9} } ) = \frac{ {4}^{2} }{ {3}^{2} } - ( - 1) = \frac{16}{9} + 1 = 1 \frac{7}{9} + 1 = 2 \frac{7}{9} [/tex]
