x = - 2

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$

Evaluating the numerator

9³ × 9 = $9^{(3+1)}$ = $9^{4}$ , thus

$\frac{9^{4} }{9^{6} }$

= $9^{(4-6)}$ = $9^{-2}$

and $9^{-2}$ = $9^{x}$

Since bases on both sides are 9, then equate exponents

x = - 2
