Đạo hàm của hàm số \(y = \dfrac{{{{ \log }_4}x}}{{x + 2}} \) là
A.\(y' = \dfrac{1}{{2x{{\left( {x + 2} \right)}^2}\ln 2}}\left( {x + 2 - x\ln x} \right)\)
B.\(y' = \dfrac{1}{{2x{{\left( {x + 2} \right)}^2}\ln 2}}\left( {x + 2 - \ln x} \right)\)
C.\(y' = \dfrac{1}{{x{{\left( {x + 2} \right)}^2}\ln 2}}\left( {x + 2 - x\ln x} \right)\)
D.\(y' = \dfrac{1}{{2{{\left( {x + 2} \right)}^2}\ln 2}}\left( {x + 2 - x\ln x} \right)\)
A.\(y' = \dfrac{1}{{2x{{\left( {x + 2} \right)}^2}\ln 2}}\left( {x + 2 - x\ln x} \right)\)
