1.³log x =³log(x+2) 2.³log (3x²+4x-4)=³log(2x+3x-2)

1. ³log x = ³log(x+2)
x = x + 2
x-x = 2
x = 2
( kalau ga salah )

2. ³log (3x² + 4x – 4) = ³log (2x + 3x – 2)
3x² + 4x – 4 = 2x + 3x – 2 3x² + 4x – 2x – 3x – 4 + 2 =
3x² – x – 2 =0
(3x + 2) (x–1) =0
x satu = 3x + 2 = 0
3x = – 2
x = – ⅔

x dua = x–1 = 0
x = 1
