пожалуйста помогите мне ​

Answer 1

Объяснение:

$\frac{ {( \frac{1}{4}) }^{3} \times 9 \times {20}^{3} }{ {18}^{4} \times {5}^{2} } = \frac{ {( {2}^{ - 2}) }^{3} \times {3}^{2} \times {2}^{6} \times {5}^{3} }{ {2}^{4} \times {3}^{8} \times {5}^{2} } = \frac{{ 2}^{ - 6} \times {3}^{2} \times {2}^{6} \times {5}^{3} }{ {2}^{4} \times {3}^{8} \times {5}^{2} } = \frac{ {3}^{2} \times {5}^{3} }{ {2}^{4} \times {3}^{8} \times {5}^{2} } = \frac{5}{ {2}^{4} \times {3}^{6} } = \frac{5}{16 \times 729} = \frac{5}{11664}$
