tolong bgt ya jawab !!! ³log140-³log35+³log45-³log1/8

3log 140 - 3log 35 + 3log 45 - 3log 1/8 = 3 log (140/35) + 3log (45×8) = 3log 4 + 3log 360 = 3log 1440.
3 nya adalah Basis

³log 140 - ³log 35 + ³log 45 - ³log (1/8)
= ³log (140 x 45 /(35 x 1/8))
= ³log (6.300 x 8/35)
= ³log 1.440 →→→→ # a #
= ³log (9 x 160)
= ³log 9 + ³log 160
= 2 + ³log 160

# a #
³log 1.440 = log 1.440 / log 3
³log 1.440 = 3,158 / 0,477
³log 1.440 = 6,62
