I want to know whats the formula to calculate the sum of the square root of integers from 1 to n.
I got an identity from wikipedia but its too complicated for me, it involves bernoulli's number, i don't know what is that.
The Attempt at a Solution
In excel i managed to get a power regression and i got the formula 0.701n^(1.492), its kind of accurate but not 100%.
I hope someone could help me.
