(\partial)/(\partial y)((2x)/(y^3))

\frac{\partial}{\partial y} (\frac{2 x}{y ^{3}})

- \frac{6 x}{y ^{4}}

Solution steps

\frac{\partial}{\partial y} (\frac{2 x}{y ^{3}})

Treat

x

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 x \frac{\partial}{\partial y} (\frac{1}{y ^{3}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 2 x \frac{\partial}{\partial y} (y^{- 3})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= 2 x (- 3 y^{- 3 - 1})

Simplify

2 x (- 3 y^{- 3 - 1}) : - \frac{6 x}{y ^{4}}

= - \frac{6 x}{y ^{4}}
