1. The problem statement, all variables and given/known data Hi, I am trying to solve this problem: I want the Big-O Estimate for this problem (n*logn + 1)^2 + (logn +1)(n^2+1) 2. Relevant equations now only real problem comes when I try to do the square of the first term. I just dont know what (n*logn)^2 would be equal, it may be a it stupid, but it completely escapes my memory how to do it. Checking on the calculator 2nlogn != (n*logn)^2 neither does n^2logn^2, so although it may be a little stupid, I just cant recall what thats equal to, I have been looking up log rules, but to no avail. 3. The attempt at a solution To me it makes sense that (n*logn)^2 = 2n*log(n) Thank You For Your Help.
