comment Using sum of logarithms of primes to prove the number of primes up to $n$ is $O(n/\log n)$
When I searched some through the net ive found many proofs, but none of them was elementary. The point in my question is to prove it using what I proved in the first exercise. I think it should be pretty elementary. If you have any hints on what I can do from here it will be very helpful.
