\(\int x^9\left(1+x^5\right)^{2 / 5} d x\) is equal to
1
\(\frac{5}{12}\left(1+x^5\right)^{12 / 5}+\frac{1}{14}\left(1+x^5\right)^{7 / 5}+C\)
2
\(\frac{1}{12}\left(1+x^5\right)^{12 / 5}-\frac{1}{7}\left(1+x^5\right)^{7 / 5}+C\)
3
\(\frac{5}{12}\left(1+x^5\right)^{12 / 5}-\frac{5}{7}\left(1+x^5\right)^{7 / 5}+C\)
4
none of these
