Hi. I have to solve the following differential equation numerically

f := [(diff(y(x), x))*(diff(y(x), x, x))/sqrt(y(x)^2+diff(y(x), x))+diff(y(x), x, x)] = x^6

dsolve({f, y(0) = 2, (D(y))(0) = 1.5, (D(D(y)))(0) = 1}, y(x), numeric, range = 0 .. 10)

Error, (in DEtools/convertsys) unable to convert to an explicit first-order system

I don't know what to do, I've read help and work on this for 3 days now.
