c

Explanation:

did it on edge

Answer 2

option C)

1/81

Explanation:

Given in the question an expression,

`9^(-2)`

Apply negative exponent rule which says

`x^(-n) = (1)/(x^(n) )`

So,

`9^(-2) = (1)/(9^(2) )`

As we know that 9² = 9x9 = 81

=
`(1)/(9x9)`

=
`(1)/(81)`

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