Answer 3

$( frac{2}{3} ) ^{5} ( {2}^{5} )^{3} {3}^{7 } div ( {2}^{10} times 3) ^{2} = \ = frac{ {2}^{5} times {2}^{15} times {3}^{7} }{ {3}^{5} } div ( {2}^{20} times 3^{2} ) = \ = ( {2}^{20} times {3}^{2} )div ( {2}^{20} times 3^{2} ) = 1$
$( frac{4}{5} ) ^{6} times ({4}^{3} )^{3} times {5}^{8} div ( {4}^{7} times 5) ^{2} = \ = frac{ {4}^{6} times {4}^{9} times {5}^{8} }{ {5}^{6} } div ( {4}^{14} times 5^{2}) = \ = ( {4}^{15} times {5}^{2} )div ( {4}^{14} times 5^{2}) = \ = {4}^{15 - 14} = 4$
