(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm fairly new to mathematica and have been trying to input the following equation, but keep getting an error message stating that I have only 2 arguments when I need 3 or more.

BTW, this is in relation to astrophysics

2. Relevant equations

function is:

f(x) = (1 / x^2) d / dx ((x^2) (df^(E-1) / dx))

where ϵ=5/3

and f(0) = 1

3. The attempt at a solution

I've put it into mathematica as

DSolve[{f[x] == ((1/x^2))* (d/dx) (x^2 * df^(ϵ - 1)/dx), x[0] == 1} f[x], x]

I've had do tidy this up a bit as when cutting & pasting mathematica seems to add extra brackets etc.

As I've stated, mathematica seems to be asking for more arguments, but I don't know what else I can add to the equation.

Thanks
