%X In this paper we investigate weighted polynomial approximations with several
variables. Our study relates to the approximation for <img src=\"Edit_fb433554-1f3d-4637-a4e6-06fc2e86f5b9.bmp\" width=\"84\" height=\"20\" alt=\"\" /> by weighted
polynomial. Then we will give some results relating to the Lagrange interpolation,
the best approximation, the Markov-Bernstein inequality and the Nikolskii-
type inequality.
