Base N Perfect Square Poser (Posted on 2016-07-13) Difficulty: 3 of 5
Consider a base-N nonzero perfect square of the form X1X1X2X2, where X1 and X2 are base-N digits whether same or different.

Derive a general formula that expresses X1X1X2X2 in terms of N, where N is an integer > 3.

*** X1X1X2X2 is a concatenation of the digits and not the product.
