__________________________________


greatest number of 4 digit is 1000


1000 Is not a perfect square


As we take a root of √ 1000 = 31 .62


hence we round of the number

which comes 32



as we know if we square 32 the digit comes in 4 digit


so


32 * 32 = 1024


hence the least four digit number is 1024
