Differentiate w.r.t. x the function

, for x > 3


Let y =

And let = u & = v


y = u + v


Differentiating both sides w.r.t. x we get


………..(I)


Now,



Taking logarithm both sides




Differentiating w.r.t. x, we get




……………(II)


Also,



Taking logarithm both sides




Differentiating both sides w.r.t. x





……………………….(II)


Substituting (II) and (III) in (I)
