derivative of f(x)=12sqrt(x^3)-1/x

Solution

derivative of

f (x) = 12 x^{3} - \frac{1}{x}

Solution

18 x + \frac{1}{x ^{2}}

Solution steps

\frac{d}{d x} (12 x^{3} - \frac{1}{x})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (12 x^{3}) - \frac{d}{d x} (\frac{1}{x})

\frac{d}{d x} (12 x^{3}) = 18 x

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

= 18 x - (- \frac{1}{x ^{2}})

Simplify

= 18 x + \frac{1}{x ^{2}}
