√1024 square root in division method

Solution

To find the square root of 10241024 using the division method (also known as the long division method), we will follow a systematic approach similar to long division.

Step-by-Step Solution:

  1. Pair the Digits from Right to Left:
    Start by pairing the digits of the number 10241024 from right to left. We get the pairs as (10)(24)(10)(24).

  2. Find the Largest Integer:
    Find the largest integer whose square is less than or equal to the leftmost pair or single digit. In this case, the leftmost part is 1010.

    • The largest integer whose square is less than or equal to 1010 is 33 (since 32=93^2 = 9 and 42=164^2 = 16 which is greater than 1010).
  3. Subtract and Bring Down the Next Pair:

    • Subtract 99 (which is 323^2) from 1010, which gives 11.
    • Bring down the next pair of digits (which is 2424), making the number 124124.
  4. Find the Next Digit of the Root:

    • Double the current quotient (which is 33) to get 66.

    • Now find a digit XX such that 6X×X1246X \times X \leq 124.

    • The suitable XX is 22 because: 62×2=12462 \times 2 = 124 This exactly matches 124124.

  5. Subtract and Check for Remainder:

    • Subtract 124124 from 124124, which gives 00.

Since there are no more pairs to bring down and the remainder is 00, the square root calculation is complete.

Result:

The square root of 10241024 is 32.
