Differentiate y = log e (log e (x))
Here e is base of log.


kvnmurty: is that Log_e (log_e x ) ? where e is the base for both Log ?
kvnmurty: or Log_e [ Log e^x] ? e power x ??
kvnmurty: what is correct ?

dy/dx=d(loge(log e (x))/dx
           =1/log e (x)   d log e (x)/dx
           =1/x log e (x) 

Utsav16: Your answer is wrong
sowmyalikhitha: oh sorry
kvnmurty: The answer is correct if the question is : y = Log [ Log x ] ... here e is treated as the base...
kvnmurty: the qn is not clear

we also write loge = ln
use this,

y = ln( ln(e^x))
differentiate wrt x
dy/dx = 1/(ln(e^x) d(lne^x)/dx

= 1/ln(e^x) × 1/e^x × d(e^x)/dx

= 1/ln(e^x) × e^x/e^x

=1/ln(e^x )

kvnmurty: 1/ Ln (e^x) is simply 1/x
kvnmurty: is the qn : y = Ln {ln e^x) ? it is simply y = Ln x as Ln e^x = x itself.
abhi178: yeah !!! right
