Answer 1

Answer:

$\sf{ (\frac{7}{6}})^{9}$

Step-by-step explanation:

$\sf{( \frac{6}{7})^{ - 5}} \times ( \frac{6}{7})^{ - 4}$

$\sf{By \: using \: the \: formula \: {a}^{m} \times {a}^{n} = {a}^{m + n}}$

$\sf{( \frac{6}{7})^{(- 5) + ( - 4)}}$

$\sf({ \frac{6}{7}})^{ - 5 - 4}$

$\sf{( \frac{6}{7}})^{ - 9}$

$\sf{ (\frac{7}{6}})^{9}$
