<br /> <br /> \frac{df}{dx} = <br /> <br /> \frac{[\frac{(30x^2 + 10x + 3)(\sqrt[3]{\frac{(4x^3 + 2x^2)}{5x^2}})}{(5)\sqrt[5]{(\frac{(10x^4 + 5x^3 + 3x^2)}{6x})^4}}] \ - \ [\frac{(\frac{(60x^4 - 20x - 20x^2)}{25x^4})(\sqrt[5]{\frac{(10x^4 + 5x^3 + 3x^2)}{6x}})}{(3)(\sqrt[3]{(\frac{(4x^3 + 2x^2)}{5x^2})^2})}]}{(\sqrt[3]{(\frac{(4x^3 + 2x^2)}{5x^2})^2})}<br />

The Attempt at a Solution



I have no idea where to even start on this! I can find simple anti-derivatives, but I'm not sure where our professor dug this one up from. He's not offering any help on it, nor any clues, either. No one in my class has any idea where to start on this, either. Most of them are just planning to skip the problem and hope it doesn't show up on the test. Any help would be greatly appreciated, as I'm sure he'll try to put something like this on the test.

Without even looking I am almost sure it will nicely cancel out and simplify if rearranged. That's one of these tricks professors love to play :smile:

Note that some terms repeat here and there.
 
Yea, I'm starting to see it now. However, if you hadn't mentioned it, I probably never would have seen it! Ha! Anyway, thanks for the pointer. I'm working on it, and I'm slowly getting there. Thanks.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
