7. Ingat sifat a pangkat log b basis a = b,
(a^log c basis a)^log a basis c (b^log 5 basis b)^log a basis 5 = (c)^log a basis c (5)^log a basis 5 = a.a = a²
Jawab : C.

8. Log(a²/b⁴) = -24
Log(a/b²)² = -24
2.log(a/b²) = -24
Log(a/b²) = -12 (kali -1)
- log(a/b²) = 12
Log(a/b²)^-1 = 12
Log 1/(a/b²) = 12
Log b²/a = 12
Log(³√(b²/a)) = log(b²/a)^⅓ = 1/3.log(b²/a) = 1/3.12 = 4
Jawab : D.
Kalau kurang jelas blh tanya, pahami lg sifat sifat logaritma ya, semoga membantu.
