heya dear let I tell you a trick to find square root of given no. first ,note down the last two digit of Number and check which number's square is near to this as here above ,last 2 digits are 60 , which is near to 7^2 ,not down 7 , and now check first two digit 12 which is near to 3^2 ,now note down 3 .
combine 3 and 7 = 37 ,this method is applicable only for perfect squared number.
