derivative of ln(ln(ln(x)))

Solution

derivative of

ln (ln (ln (x)))

Solution

\frac{1}{x ln ( ln ( x ) ) ln ( x )}

Solution steps

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

Apply the chain rule:

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

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

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

= \frac{1}{ln ( ln ( x ) )} \cdot \frac{1}{x ln ( x )}

Simplify

\frac{1}{ln ( ln ( x ) )} \cdot \frac{1}{x ln ( x )} : \frac{1}{x ln ( ln ( x ) ) ln ( x )}

= \frac{1}{x ln ( ln ( x ) ) ln ( x )}
