ANSWER :

The answer is :


7^(5x+11)

EXPLANATION :

Note that in dividing expressions with exponents and having the same bases, the exponents are subtracted from each other.


(a^x)/(a^y)=a^(x-y)

From the problem, we have :


\begin{gathered} (7^(5x+20))/(7^9)=7^((5x+20)-9) \\ =7^(5x+11) \end{gathered}
