3 log 9 - 3 log 27 tolobg jawab pakai cara

3 log 9/27 =
3 log 1/3 = -1

Rumus: 
ᵃlog a = 1
ᵃlog bⁿ = n × ᵃlog b
ᵃlog b/c = ᵃlog b  - ᵃlog c
=======================

³log 9 - ³log 27
= ³log 3² - ³log 3³
= 2 × ³log 3 -  3 × ³log 3
= 2 × 1  -  3 × 1
= 2 - 3
= -1

atau (cara 2)

³log 9 - ³log 27
= ³log (9/27)
= ³log (1/3)
= ³log 3⁻¹
= -1 × ³log 3
= -1 × 1
= -1
