we can have even number of digits.odd

if even then we have

sqrt 3005 * 10^2n = 54.8177 * 10^n

sqrt 3006* 10^2n = 54.8270 * 10^n

if odd digits then

sqrt 30050 * 10^n = 173.34 * 10^n

sqrt 30060 * 10^n= 173.37 * 10 ^n

from the 1st set we get sqrt 5482 as smallest where a digit is different and from the second at least

17335

so it is 5482^2 = 30052324
