# How to find square root of any number

Share Square root is symbolized by ( √ ) . √9 is 3 because 3×3=9.Finding Small numbers of square root is easy, For big numbers you need to learn  trick .Trick is provided bellow .after learning tricks you will be to find square root of any number.

Before going to tricks some basic examples

Some examples:-

√4=2

√16=4

√25=5

How do I calculate square root:-

Square root is done by three steps

Before starting you need to learn some basic things

12=1

22=4

32=9

42=16

52=25

62=36

72=49

82=64

92=81

102=1000

If you don’t know these don’t worry read this 4-5 times you can learn it easily

Lets move towards trick

Find  √3136

Step 1:-         √3136

Consider 1st two numbers here 31

Now take the number which square is lesser than 31

So here 62=36 greater than 31

So we find our 1st number 5

Step 2:-

Check last number     (√3136)

Here last number is   6

Again check table of squares which end came 6

Here 42=16,62 =36

So we got here 4 and 6

Step 3:-

Now 1st number (5) is multiplied by next number (5+1=6)

So 5×6=30

1st two numbers(31) are greater than 30 so between 4 or 6 big number 6 came

(*****If it is lesser than the number smaller number came )

So (√3136) =56

Taking another example it will be clear to you

Find  √1936

Step 1:-         √1936

Consider 1st two numbers here 19

Now take the number which square is lesser than 19

So here 52=25 greater than 16

So we find our 1st number 4

Step 2:-

Check last number     (√1936)

Here last number is   6

Again check table of squares which end came 6

Here 42=16,62 =36

So we got here 4 and 6

Step 3:-

Now 1st number (4) is multiplied by next number (4+1=5)

So 4×5=20

1st two numbers(19) are less than 20 so between 4 or 6 small number 4 came

So (√1936) =44
