derivative of (42)/x

Solution

derivative of

\frac{42}{x}

Solution

- \frac{42}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{42}{x})

Take the constant out:

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

= 42 \frac{d}{d x} (\frac{1}{x})

Apply exponent rule:

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

= 42 \frac{d}{d x} (x^{- 1})

Apply the Power Rule:

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

= 42 (- 1 \cdot x^{- 1 - 1})

Simplify

42 (- 1 \cdot x^{- 1 - 1}) : - \frac{42}{x ^{2}}

= - \frac{42}{x ^{2}}
