Differentiate f and find its domain. Show step by step please!
no big deal
f = ln (ln ln x)
f' = 1/(ln ln x) * (1/x * 1/ln x)
= 1/(x(lnx)(ln lnx))
what is the domain?
I was trying to solve the same question and couldn't find the domain. if someone can help me with it, I will be thankful.
what is x is negative or zero Tim ?
