\frac{d}{d x} ((x y)^{\frac{1}{2}})

\frac{y + x \frac{d y}{d x}}{2 ( x y ) ^{\frac{1}{2}}}

Solution steps

\frac{d}{d x} ((x y)^{\frac{1}{2}})

Apply the chain rule:

\frac{1}{2 ( x y ) ^{\frac{1}{2}}} \frac{d}{d x} (x y)

= \frac{1}{2 ( x y ) ^{\frac{1}{2}}} \frac{d}{d x} (x y)

\frac{d}{d x} (x y) = y + x \frac{d y}{d x}

= \frac{1}{2 ( x y ) ^{\frac{1}{2}}} (y + x \frac{d y}{d x})

Simplify

\frac{1}{2 ( x y ) ^{\frac{1}{2}}} (y + x \frac{d y}{d x}) : \frac{y + x \frac{d y}{d x}}{2 ( x y ) ^{\frac{1}{2}}}

= \frac{y + x \frac{d y}{d x}}{2 ( x y ) ^{\frac{1}{2}}}
