Hi

I have a problem to solve.


Let x(z)= a4*z^4+a3*z^3+a2*z^2+a1*z+1 be a polynomial in z.
I want the formula of the j'th derivative in z of (x(z))^(1/2). I think

this kind of problems should have been solved. But I do not
know where to find the formula. Could someone please find it for
me? Thank you very much!
