Ответ:

${( - 5)}^{10} \div {( - 5)}^{8} \times ( - 5) = {( - 5)}^{10 - 8 + 1} = {( - 5)}^{3} = - 125$

$\frac{ {( {7}^{2}) }^{15} \times ( {7}^{1} )^{19} }{ { {7}^{32} } } = \frac{ {7}^{2 \times 15} \times {7}^{1 \times 19} }{ {7}^{32} } = \frac{ {7}^{30} \times {7}^{19} }{ {7}^{32} } = {7}^{30 + 19 - 32} = {7}^{17}$

$\frac{( - \frac{1}{11} )^{4} \times ( - \frac{1}{11})^{4} } {( - \frac{1}{11})^{14} } = {( - \frac{1}{11}) }^{4 + 4 - 14} = {( - \frac{1}{11}) }^{ - 6} = {11}^{6}$

$\frac{ (\frac{1}{20})^{20} \div ( - \frac{1}{20} )^{10} }{( \frac{1}{20}) ^{4} } = \frac{ (\frac{1}{20})^{20} \div ( \frac{1}{20} )^{10} }{( \frac{1}{20}) ^{4} } = ( \frac{1}{20} )^{20 - 10 - 4} = {( \frac{1}{20} )}^{6}$
