are these (n²) ?

Solution

Theta(n^2) is the big theta notation. (n^2) means tight bound.f (n) is said to be (g(n)) iff a positive real constant C such that. f (n) Cg(n) for infinitely many values of n. The notation describes asymptotic tight bounds.

given question is is not clear.

{I =1 }^ {2^n}/ log log n

is the i= 2^n / log log n

       i = 2^n

So the given is ordre of 2.
