Unit Digits of Squares
First we need to remember unit digits of all squares from 1 to 10. The figure below shows the unit digits of the squares.

Now from the picture we can say that, whenever the unit digit of a number is 9, unit digit of the square root of that number will be definitely 3 or 7. Similarly, this can be applied to other numbers with different unit digits.

u can use prime factorization method and club every 2 prime factors (common)
after u club them find the product of it and thats ur sqr root if some some factors is left out multiply it with the product of the prime factors
for eg prime factors of 36
is 2*2*3*3 now club them as pairs now we get 2*3 which is = 6 so 6 is the sqr root of 36
