Установлено предельное равенство между наилучшими приближениями в $L_\infty$ функции многих переменных алгебраическими полиномами и целыми функциями экспоненциального типа. Встановлені гранична рівність між найкращими наближеннями в $L_\infty$ функції багатьох змінних алгебраїчними поліномами і цілими функціями експоненціального типу.
