Hello Kaushik! did you mean the following integral?
\int_{0}^{1}\frac{1}{1+x^8}dx
 this integral doesnot appear in class 12 syllabus at all!

But, if you still need an answer, i would give a solution as:
\left(\displaystyle\sum_{\left\{Z:\>Z^8+1=0\right\}}\dfrac{\ln\left(\left|x-Z\right|\right)}{8Z^7}\right)   
I could not simplify it further. Sorry!
