What does it mean when a question asks you to get a final formula?(adsbygoogle = window.adsbygoogle || []).push({});

I have an example of the question that is asking for this.

1. a) Find a reduction formula for [tex] \int(\ln x)^n dx [/tex] which I did find and got the answer: [tex]x (\ln x)^n - n \int (\ln x)^{n-1} dx [/tex].

But question part b) asks if I can use what I have in a) to get a final formula for [tex] \int(\ln x)^n dx [/tex] ? I do not understand what do they mean by a final formula?

Thanks for any help.
