The anisotropic Lebesgue space of periodic functions is considered in this paper. The exact estimate of the $M$-term of approximation function O. V. Besov's classes in the space Lebesgue with anisotropic metric is obtained in the paper.
Mots-clés : Lebesgue space, Besov's classes
Keywords: anisotropic metric.
