<prompt> Pata thamani chanya ya x ambayo inatoshelezalog_5 x - 2 logi_sqrt5 x3 - 2 logi_frac15 x - 2 4.  <response>: Kwa formula ya mabadiliko ya msingi,log_sqrt5 x3 - 2 fraclog_5 x3 - 2log_5 sqrt5 fraclog_5 x 3 - 212 2 log_5 x3 - 2,nalog_frac15 x - 2 fraclog_5 x - 2log_5 frac15 -log_5 x - 2,hivyo mlinganyo uliotolewa unakuwa2 log_5 x3 - 2 4.Kisha log_5 x3 - 2 2, hivyo x3 - 2 52 25. Kisha x 3 27, hivyo x 3.
