Answer:

x = - 2

Explanation:

Using the rules of exponents


a^(m) ×
a^(n) =
a^((m+n))


(a^(m) )/(a^(n) ) =
a^((m-n))

Evaluating the numerator

9³ × 9 =
9^((3+1)) =
9^(4) , thus


(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
