You need to find the indefinite integral, hence you need to use the following formula:

`int 1/(x^n) dx = (x^(-n+1))/(1-n)`

Replacing 5 for n yields:

`int 1/(x^5) dx = (x^(-5+1))/(1-5)`

`int 1/(x^5) dx =(x^(-4))/(-4)`

You need to remember that `x^(-n) = 1/(x^n):`

`int 1/(x^5) dx =1/(-4x^4)`

Hence, evaluating the indefinite integral, yields` int 1/(x^5) dx =1/(-4x^4).`
