Answer 1

Решение:
${20}^{3} times {0.5}^{3} = frac{ {20}^{3} }{1} times ({ frac{10}{20} )}^{3} = frac{ {20}^{3} times {10}^{3} }{1 times {20}^{3} } = {10}^{3} = 1000\ frac{4 times {2}^{5} }{ {2}^{7} } = frac{ {2}^{2} times {2}^{5} }{ {2}^{7} } = frac{ {2}^{7} }{ {2}^{7} } = 1 \ {(0.25)}^{2} times {100}^{2} = frac{ {25}^{2} times {100}^{2} }{ {100}^{2} } = {25}^{2} = 625\ frac{ {3}^{8} }{ {3}^{6} times 9 } = frac{ {3}^{8} }{ {3}^{6} times {3}^{2} } = frac{ {3}^{8} }{ {3}^{8} } = 1$
