Question

find the square root of 3969 by division methid​

Answer 1

Answer:

Step 1 : We write 3969 as

39

69

by grouping the digits into pairs, starting from right end.

Step 2 : Find the number whose square is less than or equal to 39. It is 6.

Step 3 : Put 6 on the top and also write 6 as a divisor.

Step 4 : Multiply 6 with 6 and write the result 36 under 39 and subtract. The remainder is 3.

Step 5 : Bring down the pair 69 by the side of this remainder 3, yielding 369.

Step 6 : Double 6, take the result 12 and find the number

′

n

′

. Such that 12n×n is just less than or equal to 369.

Since 122×2=244;123×3=369,n=3

Step 7 : Write 123 as the next divisor and put 3 on the top along with 6. Write the product 123×3=369 under 369 and subtract. Since the remainder is 0, the division is complete.

Hence

3969

=63.
