(\partial}{\partial z}(\frac{(x-y))/z)

\frac{\partial}{\partial z} (\frac{( x - y )}{z})

- \frac{x - y}{z ^{2}}

Solution steps

\frac{\partial}{\partial z} (\frac{( x - y )}{z})

Treat

x, y

as constants

Take the constant out:

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

= (x - y) \frac{\partial}{\partial z} (\frac{1}{z})

Apply exponent rule:

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

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

Apply the Power Rule:

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

= (x - y) (- 1 \cdot z^{- 1 - 1})

Simplify

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

= - \frac{x - y}{z ^{2}}
