$( {2}^{- 5} ) ^{ - 3} ( {2}^{- 4} ) ^{4} = {2}^{15} \times {2}^{- 16} = \\ = {2}^{ - 1} = 0.5$
$( {5}^{4} ) ^{2} \div ( {5}^{ - 3} ) ^{ - 3} = {5}^{8} \div {5}^{9} = \\ = {5}^{ - 1} = 0.2$

$( {10}^{0} ) ^{25} \div ( {10}^{ - 7}) ^{0} = {10}^{0} \div {10}^{0} = 1$
$( {5}^{ - 12} ) ^{3} \div {5}^{ - 38} = {5}^{ - 36} \times {5}^{38} = \\ = {5}^{2} = 25$
${4}^{ - 28} \div ( {4}^{8} \times {4}^{ - 17} ) ^{3} = \\ = {4}^{ - 28} \div ( {4}^{ - 9 \times 3} ) = \\ = {4}^{ - 28 + 27} = {4}^{ - 1} = 0.25$
$( {3}^{ - 6} {3}^{ - 4} ) ^{2} \div {3}^{ - 22} = \\ = ({3}^{ - 10})^{2} \div {3}^{ - 22} = \\ = {3}^{ - 20 + 22} = {3}^{2} = 9$
