How can we solve log of log ? I have this : n * (log base e (log base 2 (n)))?

Question

How can I solve this to have a better representation in order to get a Big Oh notation for this.
n * (log base e (log base 2 (n)))

Answer 1

I'd just call it O(n log log n). I don't think you can make it any simpler than that.
