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

12=1 22=4 32=9 42=16 52=25 62=36 72=49 82=64 92=81 102=1000    

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
