LOGARITMA
²log (x – 2) + ²log (x – 3) = ²log 3 .³ log 2
²log (x – 2).(x – 3) = ²log 2
(x – 2) (x – 3) = 2
x² – 3x – 2x + 6 – 2 = 0
x² – 5x + 4 = 0
(x – 1) (x – 4)
x = 1 atau x = 4
jawaban D. { 1,4 }

²log (x – 2) + ²log (x – 3) = ²log 3 . ³log 2
²log (x – 2)(x – 3) = ²log 2
(x – 2)(x – 3) = 2
x² – 5x + 6 = 2
x² – 5x + 6 – 2 = 0
x² – 5x + 4 = 0
(x – 4)(x – 1) = 0
x = 4 dan x = 1
HP = {1, 4}
