$( \frac{1}{5})^{ - 2} \times ( \frac{2}{3})^{3} \times {3}^{ - 2} \times {3}^{5}$

${5}^{2} \times ( \frac{2}{3})^{3} \times {3}^{ - 2} \times {3}^{5}$

${5}^{2} \times \frac{8}{27} \times {3}^{ - 2} \times {3}^{5}$

$25 \times \frac{8}{27} \times {3}^{ - 2} \times {3}^{5}$

$25 \times \frac{8}{ {3}^{3} } \times {3}^{ - 2} \times {3}^{5}$

$25 \times 8 \times {3}^{ - 2} \times {3}^{5 - 3}$

${3}^{5 - 3} = {3}^{2}$

$25 \times 8 \times 3 \times {3}^{ - 2} \times {3}^{2}$

$25 \times 8 = 200$

$200 \times {3}^{ - 2} \times {3}^{2}$

$200 \times {3}^{ - 2 + 2}$

$200 \times {3}^{0}$

$200 \times 1 = 200$
