First group it in twos from the right .
Then find the square root of the last no.
Then see the first digit and and find the square root of what is possible ,
Say 225 root
Take 25 and find the square root .
It will be 5
So the ones place s of ur ans is 5
Then take 2 ,1*1=1 but 2*2=4 so it is choosing the no.2,
so the one s digit is 5 and tens is 1 here the ans is 15.
But is ur taking 289 root
Root of _9 can be 3 or seven
So take the 2 and the same 1 as tens place the tans digit is less than the ans so u will take 7 is the ans is 17 .
Hope I helped
