The paper is devoted to the estimate u(x,k)Kk{capp,w(F)pw(B(x,))} 1p-1, $2p<n$ for a solution of a degenerate nonlinear elliptic equation in a domain $B(x_0,1)\setminus F$, $F\subset B(x_0,d)=\{x\in {ℝ}^n|x_0-x|<d\}$, $d<\frac{1}{2}$, under the boundary-value conditions $u(x,k)=k$ for $x\in \partial F$, $u(x,k)=0$ for $x\in \partial B(x_0,1)$ and where $0<\rho \le dist(x,F)$, $w\left(x\right)$ is a weighted function from some Muckenhoupt class, and $ca{p}_{p,w}\left(F\right)$, $w\left(B\right(x,\rho \left)\right)$ are weighted capacity and measure of the corresponding sets.
