Thread: Expressing a limit as definite Integral

Hi, I am stuck on this question that asks me to express the following limit to infinity as a definite integral.

I am sort of stuck. If let delta x=3/n and the second part equal xi, I get that it is the integral of x^9 from 0 to 8.

However shouldn't it be something else?


Thanks in advance!
