first of all make it 2 into 0 to h/2...
the obvious thing......
then [12]
I = \int^{h/2}_{-h/2} \left( \frac{4x^2}{3} + \frac{2l^2}{3} \right)^{\frac{1+n}{2n}}dx
yaar yeh ques maine kahin se dekha hai
bas itna hii given hai!!!!!!!!!!!!!!

lagta hai x2 common lena hoga,
lemme do da sum,
mani :WAS IT AN MCQ
think JEE
so lets take it as an MCQ:
1) y make life hell
==> let l = 0, n=1
I = 2 ∫(2/√3)x
I = 2h2/√3
now sub l and n in the options, chk it and NJOY [1]
