<prompt> Pata x, ikizingatiwa kwamba log_2 2018 log_4 2018 log_8 2018 log_64 2018 log_x 2018.  <response>: Acha y log_2 2018. Kisha kwa kubadilisha fomula msingi, kwa b yoyote, log_2b 2018 fraclog_2 2018log_2 2b fraclog_2 2018b.Hivyo, log_4 2018 fraclog_2 20182 frac y2, log_8 2018 fraclog_2 20183 frac y3, na log_64 2018 fraclog_2 20186 frac y6. Kwa hivyo, upande wa kushoto unakuwa y frac y2 frac y3 frac y6 kushoto1frac12frac13frac16kuliay 2y.Tukichukua btfrac12, tunaona kwamba log_212 2018 fraclog_2 201812 2y,kwa hivyo upande wa kushoto ni sawa na log_212 2018, au log_sqrt2 2018. Hivyo, x sqrt2.
