Now, the answers in the back give:

$\displaystyle 32x/(4x^2+1)$

----as the derivative. I had a problem with this Question/Answer combo... I would think that the derivative it gives would be for the function

$\displaystyle y=ln[(8x^2+2)^4]$

.... I believe there is a difference, and I would like to know if I am correct.

Because I went about solving the question a different way, due to the way I see it written (I see it as $\displaystyle y=[ln(8x^2+2)]^4$ )
