I have modified my integral a bit. But it is again not working.I have also tried to plot the function but it is showing an error.
enter code here
f[x_] := 1 - {a*x^d}
k[x_] := 1 + {b*a*{x^d}}
h[x_] := x^{d - 1}/Sqrt[f[x]*{{k[x]/k[1]} - x^{2*d - 2}}]
Integrate[h[x], {x, 0, 1}, Assumptions -> {x > 0, 0 < a < 1, b > 0, d > 2}]
it is giving the following error
{{{{Integrate[x^(-1+d)/Sqrt[(1-a x^d) (-x^(-2+2 d)+(1+a b x^d)/(1+a b))],{x,0,1},Assumptions->{x>0,0<a<1,b>0,d>2}]}}}}
