Smallest square number: 139854276
Largest square number: 923187456
Method: a (rather boring) brute-force search of all possible permutations of the digits.
If you're interested, the other square numbers you can form from the nine digits are: 152843769, 157326849, 215384976, 245893761, 254817369, 326597184, 361874529, 375468129, 382945761, 385297641, 412739856, 523814769, 529874361, 537219684, 549386721, 587432169, 589324176, 597362481, 615387249, 627953481, 653927184, 672935481, 697435281, 714653289, 735982641, 743816529, 842973156, and 847159236.
