Hàm số \(f\left( x \right) = \log \left( {{x^{2019}} - 2020x} \right)\) có đạo hàm là
A.\(f'\left( x \right) = \dfrac{{\left( {{x^{2019}} - 2020x} \right).\ln 10}}{{2019{x^{2018}} - 2020}}\)
B.\(f'\left( x \right) = \dfrac{{{x^{2019}} - 2020x}}{{\left( {2019{x^{2018}} - 2020} \right).\ln 2018}}\)
C.\(f'\left( x \right) = \dfrac{{\left( {2019{x^{2018}} - 2020} \right)\log e}}{{{x^{2019}} - 2020x}}\)
D.\(f'\left( x \right) = \dfrac{{\left( {2019{x^{2018}} - 2020} \right)\ln 10}}{{{x^{2019}} - 2020x}}\)
