Question

Найдите значение выражения (5⁴•(5•9))÷(9²•5 в седьмой степени,)

Answer 1

$\frac{ {5}^{4} \times 5 \times 9 }{ {9}^{2} \times {5}^{7} } = \frac{ {5}^{5} \times 9 }{ {5}^{7} \times {9}^{2} } = {5}^{5 - 7} \times {9}^{1 - 2} = {5}^{ - 2} \times {9}^{ - 1} = \frac{1}{ {5}^{2} \times 9 } = \frac{1}{25 \times 9} = \frac{1}{225}$
