The given expression to us is:
(3²)⁻²
In this expression, the two powers, which are 2 and -2, are multiplying with each other, we can write it as:
(3)⁻⁴
Now we know that a negative power of a number can be converted into a positive power one if we take reciprocal of the given number.
It can be written as:
(1/3)⁴
Further simplify the expression:
1/81
Thus the correct choice from the given options is:
1 over 81 or 1/81
