Question

log3x-log9x=3/2
Решите уравнение

Answer 1

1/n loga x = logaⁿ x

log3 x - log9 x = 3/2

log3 x - log3² x = 3/2

log3 x - 1/2 log3 x = 3/2

1/2 log3 x = 3/2

log3 x = 3

log3 x = log3 27

x = 27

Answer 2

Ответ: 27

Пошаговое объяснение:

log3 x-1/2log3 x=3/2,   1/2log3 x=3/2,  log3 x=3,  x=3^3=27
