Find the derivative of \(\rm f(x)=\left(1+x^4-\frac{1}{x}\right)^{\frac{5}{3}}\)
1
\(\rm \frac{20}{3}\times \frac{11}{3}+\frac{5}{3x^{8/3}}\)
2
\(\rm \frac{5}{3}\left(1+x^4+\frac{1}{x}\right)\frac{2}{3}\)
3
\(\rm \frac{5}{3}\left(1+x^4-\frac{1}{x}\right)^{\frac{2}{3}}\left(4x^3+\frac{1}{x^2}\right)\)
4
\(\rm \frac{5}{3}x^{2/3}\left(4x^3+\frac{1}{x^2}\right)\)
