Answer 1

Step-by-step explanation:

Let y = x^{\frac{1}{x} }y=x

x

1

Take log on both side

log(y) = \frac{1}{x}log(x)log(y)=

x

1

log(x)

Now differentiate bothe side w.r.t x

\frac{1}{y} \frac{dy}{dx}= \frac{1-logx}{x^{2} }

y

1

dx

dy

=

x

2

1−logx

\frac{dy}{dx} = y(\frac{1-logx}{x^{2} } )

dx

dy

=y(

x

2

1−logx

)

\frac{dy}{dx} = x^{\frac{1}{x} } (\frac{1-logx}{x^{2} } )

dx

dy

=x

x

1

(

x

2

1−logx

)
