Answer:
9^-2 or 1/81
Step-by-step explanation:
Exponent Rule:
When dividing exponents, they're subtracted.
Since the second term has a negative exponent, we add.
Change the problem into multiplication, then add 4 to the exponent of -6:
[tex]\frac{9^{-6} }{9^{-4} } = 9^{-6} \times 9^{4}=9^{-2}[/tex] [tex]or[/tex] [tex]\frac{1}{81}[/tex]
