Best ResponseYou've already chosen the best response.0So let's just start from scratch, I'll bet we can figure this out. \[\large \int\limits_1^k x^{n1}dx\]Taking the integral gives us,\[\huge \frac{1}{n}x^n_1^k\] Evaluated at k and 1 gives us (I'm factoring the 1/n out first),\[\large \color{purple}{\frac{1}{n}\left(k1\right)}\] And they're asking, When does \(\color{purple}{\textbf{this}}\) equal \(\dfrac{1}{n}\)
