I am not sure if I am on the right track with this problem and where do i go from here. Please help.
Problem: y=4x^2(7x^2+8)^(-2/3) find dy/dx. This is my solution so far:
-8x^2(14x/3(7x^2+8)^(5/3) + 8x/(7x^2+8)^(2/3)
-112x^3/3(7x^2+8)^(5/3) + 8x/(7x^2+8)^(2/3)
Where do I go from here?
Thank you in advance. Any help is greatly appreciated.
So was I on the wrong track or was I just going about it in a longer version? So the answer is [IMG]file:///C:/Users/Michelle/AppData/Local/Temp/moz-screenshot.jpg[/IMG]8x(7x^2 +24) over 3(7x^2 +8)^(5/3)? If so, eventually would I have gotten to that answer on the path I was taking? Thank you for your help.
