minta tolong gaissssss
Jawab:
logaritma
ᵃlog b = ⁿlog b/ⁿlog a
⁵log 3 = a dan ³log 4 = b
nilai ⁴⁵log 12 =
[tex]\sf= \dfrac{^3log 12}{^3log 45}[/tex]
[tex]\sf = \dfrac{^3log 3+^3log 4 }{^3log 3^2+ ^3log 5}[/tex]
[tex]\sf = \dfrac{1+b }{2+ \frac{1}{a}}[/tex]
kalikan a/a
[tex]\sf = \dfrac{a+ ab}{2a+ 1}[/tex]
