N is a perfect square containing precisely one 3, two 2’s and three 1’s. Any of the other seven digits may or may not occur in N.

Determine the smallest two values of N.

(In reply to computer solution -- smallest nine values by Charlie)

Nothing wrong with the answers, but the labels are misleading,

it is not sqrt(n) and n squared, it should be  N  ^ &  N^2:  not too late to edit.
