Question 272565
To evaluate:

9 to the negative power of 2

Looks like this:

{{{9^-2}}}

Now, you cannot leave your answer in that form, you have to change it.
Here's how:

Move the 9 to the denominator, this changes the sign, power of 2 to positive
{{{1/9^2}}}

To simplify further, multiply 9 x 9 (power of 2) to equal 81:

{{{1/81}}}
