64 (8*8) and (4*4*4)
The next one is 81 (9*9) and (3*3*3) :)

The smallest integer is 11 but there is no smallest number! 0.11 is a smaller number and will give a perfect square. 0.0011 is smaller still, and 0.000011 even smaller. That sequence is endless!
69
The number/digit 2.
The smallest perfect square is 121.

The smallest square number qreater than 1 is 2. * * * * * 2 is not a perfect square number.
its 81
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.
