[tex]\int_9^{inf} \frac{1}{x^{6/5}}[/tex]
first thing i did was found the integral of the function
[tex]\frac{5}{x^{-1/5}}[/tex]
then plug in inf(i will name it b) and 9
[tex]\frac{5}{b^{-1/5}} - \frac{5}{9^{-1/5}}[/tex]
now i will find the lim -> inf
well for [tex]\frac{5}{9^{-1/5}}[/tex], it's equal to 7.759
now for [tex]\frac{5}{b^{-1/5}}[/tex], it looks like INF, but when i try to submit my answer, it tells me that I'm wrong.
anyone know what I'm doing wrong?
