Ответ:

${( \frac{1}{4}) }^{2} = \frac{ {1}^{2} }{ {4}^{2} } = \frac{1}{16} \\ {( \frac{3}{8}) }^{2} = \frac{ {3}^{2} }{ {8}^{2} } = \frac{9}{64} \\ {( \frac{5}{6}) }^{2} = \frac{ {5}^{2} }{ {6}^{2} } = \frac{25}{36} \\ {( \frac{2}{7} )}^{2} = \frac{ {2}^{2} }{ {7}^{2} } = \frac{4}{49} \\ {(1 \frac{1}{2}) }^{2} = {( \frac{3}{2} )}^{2} = \frac{ {3}^{2} }{ {2}^{2} } = \frac{9}{4} = 2 \frac{1}{4} \\ {(4 \frac{1}{9}) }^{2} = {( \frac{37}{9} )}^{2} = \frac{ {37}^{2} }{ {9}^{2} } = \frac{1369}{81} = 16 \frac{73}{81} \\ {(6 \frac{2}{3} )}^{2} = {( \frac{20}{3} )}^{2} = \frac{ {20}^{2} }{ {3}^{2} } = \frac{400}{9} = 44 \frac{4}{9}$

${( \frac{1}{2}) }^{3} = \frac{ {1}^{3} }{ {2}^{3} } = \frac{1}{8} \\ {( \frac{2}{3}) }^{3} = \frac{ {2}^{3} }{ {3}^{3} } = \frac{8}{27} \\ {( \frac{1}{5}) }^{3} = \frac{ {1}^{3} }{ {5}^{3} } = \frac{1}{125} \\ {( \frac{4}{9}) }^{3} = \frac{ {4}^{3} }{ {9}^{3} } = \frac{64}{729} \\ {(1 \frac{1}{3}) }^{3} = \frac{ {4}^{3} }{ {3}^{3} } = \frac{64}{27} = 2 \frac{10}{27} \\ {( 2\frac{1}{4}) }^{3} = \frac{ {9}^{3} }{ {4}^{3} } = \frac{729}{64} = 11 \frac{25}{64} \\ {( 3\frac{1}{2}) }^{3} = \frac{ {7}^{3} }{ {2}^{3} } = \frac{343}{8} = 42 \frac{7}{8}$
