mark a bar on two digits from th unit digit on top.
now see that 6 is divisible by which square number(i mean 2*2 ,3*3.....)
so its 2
you just put 625 into division symbol
2
2/625
/ 4(subtract 4 from 6)
/225
multiply the quotient x2
so you get 4
now see the following
41*1=41
42*2=84
43*3=129
44*4=176
45*5=225
so
25
2 /625
/ 4
45 /225
/225

what is square root ?
The square root of a number is any value when multiplied by itself, gives the number. Pretty simpler definition
How do you find Square Root ?Well, its not such a complicated thing as you have been thinking. Trust me, After reading this post you surely will be able to calculate square root of any number.Before going to find the square root of any number, you should check whether the given number is a square or not.Check the units place (right most digit) of the given number. If you find2, 3, 7and8at the unit place then the given number isnot a square numberand you can't find square root for the given number.Ex : 652 is not a square number because there is 2 at the unit place of the number.So, if the number ends with1, 4, 5, 6, 9and0thenthe given number is a square numberand you can find square root of the given number (Ofcourse, There are some exceptions with 0).Now you have got a number to find its square root. Which is having one of these numbers 1, 4, 5, 6, 9 at the end. Now check the below table. Just try to remember it. Ofcourse, you easily can remember the values. Can't you ? :)Units PlaceFactors11 or 942 or 85564 or 693 or 700It simply says,if the given number has 1 at the unit's place, then its square root will have 1 or 9 at the end (this is because 1x1 =1and 9 x 9 = 81)if the given number has 4 at the unit's place, then its square root will have2 or 8 at the end (this ie because 2x2 =4and 8x8 = 64)You know the logic behind 5for 6, you will have 4 or 6 (4x4 = 16and 6x6 = 36)9, you will get 3 or 7 (3x3 =9and 7x7 = 49)Ok, now come to the actual method of finding square roots of the given number.Inorder to find the square root of the given number, you just should remember the following manthra. Just mug-up the following four lines.- Nearest Square
- Its root ----------- this will be the first number of our square root.
- Its double
- Join the factor and multiply with it-------- the factor will be the second number of our square root
