Materi : Logaritma
Kelas : X SMA

^3 log81 + ^3 log81 - ^3 log27
》4 + 4 - 3
》8 - 3
》5

SIfat Logaritma:
ᵃlog a = 1
ᵃlog b + ᵃlog c = ᵃlog(b.c)
ᵃlog b - ᵃlog c = ᵃlog(b/c)

==Jawaban==
³log81 + ³log81 - ³log27
= ³log(81.81) - ³log27
= ³log6561 - ³log27
= ³log(6561/27)
= ³log243
= ³log3⁵
= 5.³log3
= 5.1
= 5
