9^-2 = 1/81 or 0.0123
When there is a negative in front of the exponent it makes a fraction. It is usually just 1/the number it equals if it were positive.

Answer:

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

Step-by-step explanation:

express that with a positive exponent using this:

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

so ..

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

now you have to evaluate the exponent/ power

so..

[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]

why 81 ?

because the exponent of 9 is 2 so you have to multiple 9 by itself so

9x9=81

so the answer is

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

sorry for the bad english hehe
