Question

I would like to know if there is an easy way to solve this or at least with th calculator......Jijiji!!
∫[4,1,(t^(7)-t^(3))/(t^(5))dx]
Thanks!! (I made a mistake.)

Answer 1

I gives it me another answer.. I am confused.. Please help!!

Answer 2

The answer that it gave me is deifferent. Is 81/4

Answer 3

I wrote it wrong...
\[\int\limits_1^4 \frac{t^7-t^3}{t^5}dt=\int\limits_1^4 t^2-t^{-2} dt = \frac{t^3}{3}+t^{-1}|_1^4=\frac{1}{3}(4^3-1)+(\frac{1}{4}-1)=81/4\]
