  1. Enter 1000 into the calculator.
  2. Press the square root function (√).
  3. The calculator displays the result: approximately 31.622.

Prime Factorization Method

The Prime Factorization Method involves breaking down 1000 into its prime factors and then simplifying the square root expression. Here are the detailed steps:

  1. Find the prime factors of 1000:
    • 1000 is an even number, so it is divisible by 2.
    • Divide 1000 by 2: \(1000 \div 2 = 500\)
    • 500 is also even, so divide by 2: \(500 \div 2 = 250\)
    • 250 is even, so divide by 2 again: \(250 \div 2 = 125\)
    • 125 is not even but ends in 5, so it is divisible by 5.
    • Divide 125 by 5: \(125 \div 5 = 25\)
    • 25 is divisible by 5: \(25 \div 5 = 5\)
    • 5 is a prime number and can be divided by itself: \(5 \div 5 = 1\)
  2. Write 1000 as the product of its prime factors:

    \[1000 = 2 \times 2 \times 2 \times 5 \times 5 \times 5\]

  3. Group the prime factors into pairs:

    \[1000 = (2 \times 2 \times 2) \times (5 \times 5 \times 5)\]

  4. Simplify the expression:

    \[1000 = 2^3 \times 5^3\]

  5. Take the square root of both sides:

    \[\sqrt{1000} = \sqrt{2^3 \times 5^3}\]

    \[\sqrt{1000} = \sqrt{(2 \times 5)^2 \times 10}\]

    \[\sqrt{1000} = \sqrt{100} \times \sqrt{10}\]

    \[\sqrt{1000} = 10 \times \sqrt{10}\]

Thus, the square root of 1000 can be simplified to \(10\sqrt{10}\).

Long Division Method

The long division method is a systematic way to find the square root of a number, which can be used for both perfect and non-perfect squares. Here are the detailed steps to find the square root of 1000 using the long division method:

  1. Write the number in decimal form: Start by writing 1000 as 1000.000000 to ensure precision up to several decimal places. Pair the digits from right to left, placing a bar over each pair.

  2. Initial division: Find the largest number whose square is less than or equal to the first pair. For 10, this number is 3 (since 3×3=9). Write 3 as the quotient and 9 as the product below the first pair (10). Subtract to get the remainder 1.

  3. Double the quotient: Double the current quotient (3), resulting in 6. This is the beginning of the new divisor.

  4. Bring down the next pair: Bring down the next pair of digits (00), giving a new dividend of 100. Determine the largest digit X such that (60 + X) × X is less than or equal to 100. Here, X is 1, so the new divisor is 61.

  5. Subtract and repeat: Subtract 61 from 100, giving a remainder of 39. Bring down the next pair of zeros (00), making the new dividend 3900. Double the quotient part obtained so far (31), giving 62. Find X such that (620 + X) × X is less than or equal to 3900. Here, X is 6, so the new divisor is 626.

  6. Continue the process: Subtract 3756 from 3900, giving a remainder of 144. Repeat the process by bringing down pairs of zeros and finding appropriate X values, updating the quotient and divisor each time.

  7. Obtain the result: Continue this process until the desired precision is achieved. The square root of 1000 using the long division method is approximately 31.622.

The long division method provides a systematic approach to finding the square root, yielding accurate results step-by-step.
