ПОМОГИТЕ ПОЖ!!! Решите уравнение: log по основанию1/3 x+2=3log по основаниюx 1/3
Решение log(1/3) (x) + 2 = 3*log(1/3) (x) log(1/3) (x) + 2 = 3*log(1/3) (x) 3*log(1/3) (x) - log(1/3) (x) = 2 log (1/3) (x)^3 - log(1/3) (x) = 2 log (1/3) ((x)^3) / (x)) = 2 x^2 = (1/3)^2 x^2 = (1/9) x1 = -1/3 x2 = 1/3
