(\partial)/(\partial x)((xy)^{(1/2)})

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

\frac{y ^{\frac{1}{2}}}{2 x ^{\frac{1}{2}}}

Solution steps

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

Treat

y

as a constant

Apply the chain rule:

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

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

\frac{\partial}{\partial x} (x y) = y

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

Simplify

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

= \frac{y ^{\frac{1}{2}}}{2 x ^{\frac{1}{2}}}

What is (\partial)/(\partial x)((xy)^{(1/2)}) ?
The answer to (\partial)/(\partial x)((xy)^{(1/2)}) is (y^{1/2})/(2x^{1/2)}
