This the simplest trick to find square of any no.
lets solve (53)²
1) square second digit i.e 3²= 9
2) now multiply first digit with second and then multiply it with 2 i.e is 5*3*2= 30
3) Now take 3 as remainder from 30
4) Square first digit and add remainder in it i.e is 25+3 = 38
5) Now arrange digits we have found from backside and we get 3809
U can use this method to find square of any number.
