The smallest square number qreater than 1 is 2. * * * * * 2 is not a perfect square number.
No. The smallest 2 digit number is 10 the smallest 3 digit number is 100 - so the question is whether (100-10) is a perfect square? No - 90 is not a perfect square. 8x8 is 64 and 9x9 is 91, not 90.
The answer is 230.
