Answer:


(3a)^(-2) =
(1)/(9(a)^(2) ).

Explanation:

Given :
(3a)^(-2).

To find : Equivalent expression .

Solution : We have given that
(3a)^(-2).

By the negative exponent rule :
x^(-m) =
(1)/(x^(m) ).

On applying this rule ,


(3a)^(-2) =
(1)/((3a)^(2) ).


(3a)^(-2) =
(1)/(9(a)^(2) ).

Therefore,
(3a)^(-2) =
(1)/(9(a)^(2) ).
