I tried this derivative problem, but the back of the book shows a different answer then what I got. Can someone explain what I'm doing wrong.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]3T^5 -5T^.5 + \frac{7}{T}[/tex]

So I did this:

[tex]15T^4 - 2.5T^-.5 - 7T^-8 [/tex]

It's the last part I got wrong I'm not sure why. I converted 7/T to T^-7. Is that right?
