$$\ \Huge F(x)=\sqrt[4]{1+2x+x^3} .$$ $\ \large \text{The answer I got was:} \frac{1}{4}(x^3+2x+1) \times (3x^2+2) .$ $\ \large \text{Is this correct?}$

So when you applied the power rule, you changed it to a 1/4 power, but then you didn't subtract 1 from the power, you actually increased it by 3/4. The new power should be 1/4 - 1, simply that :D

$$\ \text{Oh that's a typo on my part, I have} -\frac{3}{4} \text{as my final answer.}$$
