Answer 1

$Answer: \\ \\ = \frac {{3}^{-5} \times {10}^{-4} \times {5}^{4}}{{5}^{2} \times {6}^{-5}} \\ \\= \frac {{3}^{-5} \times {5}^{-4} \times {2}^{-4} \times {5}^{4-2}}{{2}^{-5} \times {3}^{-5}} \\ \\ = {3}^{-5+5} \times {5}^{-4+2} \times {2}^{-4+5} \\ \\ = 1 \times {5}^{-2} \times {2}^{1} \\ \\ = \frac {2}{{5}^{2}} \\ \\ = \frac {2}{25}$
