\frac{d}{d x} (lo g_{10} (x^{2}))

\frac{2}{ln ( 10 ) x}

Solution steps

\frac{d}{d x} (lo g_{10} (x^{2}))

Apply log rule:

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

= \frac{d}{d x} (\frac{ln ( x ^{2} )}{ln ( 10 )})

Take the constant out:

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

= \frac{1}{ln ( 10 )} \frac{d}{d x} (ln (x^{2}))

Apply the chain rule:

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

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

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

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

Simplify

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

= \frac{2}{ln ( 10 ) x}
