StartFraction 1 Over 81 EndFraction

Step-by-step explanation:

To get the equivalent expression for 9^-2, we will use the law of indices to solve it.

First we will remove the minus sign at the power, the removal of this sign will convert the value into a fraction. For example, one of the law of indices states;

a^-n = 1/a^n

Applying this law to the value given;

9^-2 = 1/9²

Next is to find the square of 9

9² = 9×9 = 81

Therefore our final answer will give;

9^-2 = 1/9²

= 1/81

The answer is B. StartFraction 1 Over 81 EndFraction
