Hi there. Can anybody solve this integral: $\displaystyle \int \frac {x^7}{\sqrt{1-x^{16}}}\,dx\$ Thank you.

P.s number under square of root is x^16. put $\displaystyle x^8 = t$ differntiating both sides $\displaystyle 8x^7dx = dt $ so integral becomes $\displaystyle \int {\frac{dt}{8 \sqrt{1-t^2}}} $ go ahead
