Hàm số \(f \left( x \right) = { \log _2} \left( {{x^2} - 2x} \right) \) có đạo hàm:
A.\(f'\left( x \right) = \frac{{\ln 2}}{{{x^2} - 2x}}\)
B.\(f'\left( x \right) = \frac{1}{{\left( {{x^2} - 2x} \right)\ln 2}}\)
C.\(f'\left( x \right) = \frac{{\left( {2x - 2} \right)\ln 2}}{{{x^2} - 2x}}\)
D.\(f'\left( x \right) = \frac{{2x - 2}}{{\left( {{x^2} - 2x} \right)\ln 2}}\)
A.\(f'\left( x \right) = \frac{{\ln 2}}{{{x^2} - 2x}}\)
B.\(f'\left( x \right) = \frac{1}{{\left( {{x^2} - 2x} \right)\ln 2}}\)
C.\(f'\left( x \right) = \frac{{\left( {2x - 2} \right)\ln 2}}{{{x^2} - 2x}}\)
D.\(f'\left( x \right) = \frac{{2x - 2}}{{\left( {{x^2} - 2x} \right)\ln 2}}\)
