Answer:

option C)

1/81

Step-by-step explanation:

Given in the question an expression,

[tex]9^{-2}[/tex]

Apply negative exponent rule which says

[tex]x^{-n} = \frac{1}{x^{n} }[/tex]

So,

[tex]9^{-2} = \frac{1}{9^{2} }[/tex]

As we know that 9² = 9x9 = 81

= [tex]\frac{1}{9x9}[/tex]

= [tex]\frac{1}{81}[/tex]

So, the expression 9^-2 = 1/81
