As we know that least 6th digit no. is 100000.
then square root of 100000 will be =√100000
= 100√10

soniasandeshp8lmi1: wrong answer

AkashDewangan: yes , thanks for telling me , i actually forgot the second part ......IT IS CONTINUATION OF THE Q. we have to see what number should be added or subtracted to √10 (NOT 100000) which will make it a perfect square , THAT IS = √10-√6= √4 = 2 HENCE 2 Should BE MULTIPLIED WITH 100000 TO GET GET THE PERFECT SQUARE THAT IS 200000

AkashDewangan: IT IS AN EASY METHOD TO FIND ONE OF THE SMALLEST 6TH DIGIT SQUARE NO. OR ELSE

AkashDewangan: WE HAVE TO FIND THE Value OF 100√10 = 316.227(APPROX) BUT, 316 IS EQUAL TO 99859 WHICH AIS A Digit NO. SO WE WILL TAKE NEXT NO. WHICH IS 317 WHICH IS EQUAL TO 100489 , hence it is the least 6 digit perfect square
