Narrative:
Lax approach control cleared us to maintain 180 kias to limma; cleared visual 25L. Tower frequency was preset on VHF #1 in standby mode and forgot to obtain landing clearance from lax tower. Attributing to our error was: not being told to contact tower by approach; encountering some wake turbulence from preceding 737 on final while captain was hand flying/adjusting to a slightly higher glide path to avoid; possibly some fatigue from our 10hr duty day/7.5hr flight time/day 4 of the trip after a 12hr layover; following an [early] arrival the day before.
