Find the greatest 6 digit number which is a perfect square??
The greatest six digit number = 999,999
we know that 10002 = 1,000,000 which is only 1 more than 999,999
so the greatest six digit number which is perfect square = (1000 -1)2
= ( 999)2
= 998,001
Answer is 998,001.
Hope this helps you
thanks
