Putar basis:
1/⁵log(4x-3x²) < 0
Sehingga
⁵log(4x-3x²) < 0
⁵log(4x-3x²) < ⁵log 1
4x - 3x² < 1
3x² - 4x + 1 > 0
(3x-1)(x-1) > 0
Didapat selesaian:
x < 1/3 atau x > 1
Agar basis tetap positif,
4x - 3x² > 0
x(4-3x) > 0
x(3x-4) < 0
Sehingga,
0 < x < 4/3
Dengan irisannya, didapat:
0 < x < 1/3 atau 1 < x < 4/3
