Is anybody interested in this problem? Solve This One: Victor Niederhoffer in "Education of a Speculator," recalls that he wanted to join his Brooklyn High School Math Team, and prepair for a hope-for entrance to Harvard University, which he achieved. He mentions that he was asked to solve in about a minute this problem, (2+(5)^.5)^1/3 + (2-(5)^.5)^1/3 = ? Niederhoffer knew he could not do it, but since it was a multiple choice question he eliminated answers containing pi and e, and guessed the right remaining one. He once sent me an autographed copy of his book, and I have always enjoyed this math question. Does anyone know the answer?
