Answer:

Option C is correct

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

Step-by-step explanation:

Given the expression:

[tex](3^2)^{-2}[/tex]

We can write [tex]3^2[/tex] as:

[tex]3^2 = 3 \cdot 3 = 9[/tex]

then;

[tex](9)^{-2}[/tex]

Using the exponent rule:

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

then;

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

⇒[tex]\frac{1}{81}[/tex]

Therefore, the expression which is equivalent to [tex](3^2)^{-2}[/tex] is, [tex]\frac{1}{81}[/tex].
