Answer 2

Answer:

-8

Step-by-step explanation:

$({ \frac{1}{5}) }^{ - 3} \times { (\frac{1}{5}) }^{ - 5} = { (\frac{1}{5} )}^{x} \\ \\ {( \frac{a}{b}) }^{m} \times { (\frac{a}{b}) }^{n} = {( \frac{a}{b}) }^{m + n} \\ \\ {( \frac{1}{5}) }^{( - 3) + (- 5)} = { (\frac{1}{5}) }^{x} \\ \\ {( \frac{1}{5}) }^{ - 8} = { (\frac{1}{5} )}^{x} \\ \\ x = (- 8)$
