а) log x 4 = 1/3Преобразуем уравнение:log x 4 = 1/34 = x^(1/3)4^3 = x64 = x
Ответ: x = 64
б) lg x = 1/2 lg 9 - 2/3 lg 8lg x = lg(9^(1/2)) - lg(8^(2/3))lg x = lg(3) - lg(4)lg x = lg(3/4)x = 3/4
Ответ: x = 3/4
а) log x 4 = 1/3
Преобразуем уравнение:
log x 4 = 1/3
4 = x^(1/3)
4^3 = x
64 = x
Ответ: x = 64
б) lg x = 1/2 lg 9 - 2/3 lg 8
lg x = lg(9^(1/2)) - lg(8^(2/3))
lg x = lg(3) - lg(4)
lg x = lg(3/4)
x = 3/4
Ответ: x = 3/4
