LATIHAN SOAL PERTIDAKSAAN LOGARITMA

x+akar3 > 0
x > -akar3

x-akar3 > 0
x > akar3

'1/3log(x+akar3) + '1/3(x-akar3) > 0
'1/3log(x+akar3)(x-akar3) > 0
'1/3log(x+akar3)(x-akar3) > 1/3log1
(x+akar3)(x-akar3) < 1
x^2 - 3 < 1
x^2 - 4 < 0
(x-2)(x+2) < 0
-2 < x < 2

penyelesaiannya (irisan)
akar3 < x < 2
