hello, I am going to assume that the -3 is the power in this case.

In order to make it positive, we need to move it to the bottom of the fraction (to the denominator) and make is positive

So, final answer simplified would be

1/(5x-1)^3

All the best.. Request me anytime by putting "For Greg" at the front of your post.

Right. When you have a negative exponent, you move it to the other part of the fraction and make it positive.

For instance, if I had x^-3 I would move the x^-3 to the bottom (denominator) and make the power positive so it would be 1/x^3

Likewise, if the negative power is on the bottom, we move it to the top and make it positive

So, if we had 1/x^-3 then we should move the x^-3 to the numerator and make it positive so the answer would just be x^3 since we do not show 1 as the denominator.

Does that help?
