Answer 2

1.
$frac{ {9}^{5} times {27}^{8} }{ {81}^{9} } = frac{ { ({3}^{2}) }^{5} times { ({3}^{3}) }^{8} }{ {( {3}^{4}) }^{9} } = \ = frac{ {3}^{10} times {3}^{24} }{ {3}^{ 36} } = frac{ {3}^{34} }{ {3}^{36} } = frac{1}{ {3}^{2} } = frac{1}{9}$
2.
${( frac{3}{7}) }^{8} times {( 2frac{1}{3}) }^{10} = frac{ {3}^{8} }{ {7}^{8} } times {( frac{7}{3} )}^{10} = \ = frac{ {3}^{8} }{ {7}^{8} } times frac{ {7}^{10} }{ {3}^{10} } = \ = frac{ {3}^{8} times {7}^{10} }{ {7}^{8} times {3}^{10} } = \ = frac{ {7}^{2} }{ {3}^{2} } = \ = frac{49}{9} = 5 frac{4}{9}$
