derivative of f(x)=sqrt(21x)

Solution

derivative of

f (x) = 21 x

Solution

\frac{21}{2 x}

Solution steps

\frac{d}{d x} (21 x)

Apply the chain rule:

\frac{1}{2 21 x} \frac{d}{d x} (21 x)

= \frac{1}{2 21 x} \frac{d}{d x} (21 x)

\frac{d}{d x} (21 x) = 21

= \frac{1}{2 21 x} \cdot 21

Simplify

\frac{1}{2 21 x} \cdot 21 : \frac{21}{2 x}

= \frac{21}{2 x}
