The well-defined digit (Posted on 2017-08-14) Difficulty: 1 of 5
Let k denote the positive square root of 2.
What is the 144-th digit of (-1+k) 2017 ?

I found this problem with some other parameters – same level of difficulty !

So, hold your breath, do not rush to omnipotent computer, – use your brains,
an easy trick does it.
