Answer 2

`(1)/(n^(18)) = (n^(-3))^6`

Explanation:

Given

`(1)/(n^(18))`

Required

Determine its equivalent

`(1)/(n^(18))`

Express 18 as 3 * 6

`(1)/(n^(18)) = (1)/((n^(3))^6)`

This can be rewritten as:

`(1)/(n^(18)) = ((1)/(n^(3)))^6`

Apply the following law of indices:'

`(1)/(a^b) = a^(-b)`

`(1)/(n^(18)) = (n^(-3))^6`

Hence;

(d) is correct
