derivative of

lo g_{10} (\frac{x + 1}{x})

- \frac{1}{ln ( 10 ) x ( x + 1 )}

Solution steps

\frac{d}{d x} (lo g_{10} (\frac{x + 1}{x}))

Apply log rule:

lo g_{a} (b) = \frac{ln ( b )}{ln ( a )}

= \frac{d}{d x} (\frac{ln ( \frac{x + 1}{x} )}{ln ( 10 )})

Take the constant out:

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

= \frac{1}{ln ( 10 )} \frac{d}{d x} (ln (\frac{x + 1}{x}))

Apply the chain rule:

\frac{1}{\frac{x + 1}{x}} \frac{d}{d x} (\frac{x + 1}{x})

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

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

= \frac{1}{ln ( 10 )} \cdot \frac{1}{\frac{x + 1}{x}} (- \frac{1}{x ^{2}})

Simplify

\frac{1}{ln ( 10 )} \cdot \frac{1}{\frac{x + 1}{x}} (- \frac{1}{x ^{2}}) : - \frac{1}{ln ( 10 ) x ( x + 1 )}

= - \frac{1}{ln ( 10 ) x ( x + 1 )}

\frac{x ^{2}}{( x ^{2} - e )}

(x^{2})^{x}

\frac{x + 1}{2}

\frac{2 x ^{2}}{x}

x^{2} + x^{2} + 1
