Short Trick
To Find 8281
last digit 1 can be obtained from 1² or 9²
so last digit will be 1/9
now cross last two digits from end we get 82
find nearest square less than 82 i.e 9²=81<82
so 9 is first digit
and 9*next =9*10=90>82 or 82 is less than 90 so less number for last digit i.e 1 is taken
Finally 91 is answer
