Mnta tlong dong mas/mba 3 log (X-1)= 2 log 3. 3 log 4

Kelas 10 Matematika
Bab Logaritma

^ = pangkat

^3log (x - 1) = ²log 3 . ^3log 4
^3log (x - 1) = ²log 4
^3log (x - 1) = ²log 2²
x - 1 = 3^2
x = 9 + 1
x = 10

³log (x - 1) = ²log 3 . ³log 4

ingat bahwa :
[tex] ^a \log b \cdot ^b \log c = ^a \log c [/tex]

maka
³log (x - 1) = ²log 4
³log (x - 1) = 2
(x - 1) = 3²
x = 9 + 1
x = 10
