Given,
⇒ 3(log 5 - log 3) - (log 5 - 2 log 6) = 2 - log x
⇒ 3log 5 - 3log 3 - log 5 + 2 log 6 = 2 - log x
⇒ 2log 5 - 3log 3 + 2log 6 = 2 - log x
⇒ 2log 5 - log 33 + log 62 = 2 - log x
⇒ log 52 - log 27 + log 36 + log x = 2
⇒ log 25 + log 36 + log x - log 27 = 2
⇒ log = 2
⇒
⇒ 100x = 3 × 102
⇒ 100x = 300
⇒ x = = 3.
Hence, x = 3.
