The other day, Jim excitedly told me, "Did you realise I will turn x years old in the year x^2?"

He wasn't the first to think of this. The 19th century mathematician August de Morgan used to used to boast that he was x years old in the year x^2. He died in 1871.

In what year was Jim born? When will his prediction be true? In what year was de Morgan born? What is x in each case?

By the way Gamer, how did you get that ? I mean how can you say that Jim would have to be 111 years old for my second answer to be true ? Can you please explain ?
