%283x%29%5E%28-4%29+=+%283x%2F1%29%5E%28-4%29 Rewrite 3x as 3x%2F1

%283x%29%5E%28-4%29+=+%281%2F%283x%29%29%5E%284%29 Flip the fraction 3x%2F1 ---> 1%2F%283x%29 to make the exponent positive

%283x%29%5E%28-4%29+=+%281%5E4%29%2F%28%283x%29%5E4%29

%283x%29%5E%28-4%29+=+%281%29%2F%2881x%5E4%29 where x%3C%3E0
