Methods to Calculate the Square Root of 200

The square root of 200 can be calculated using several methods, each offering different levels of precision and understanding. Below are the most commonly used methods:

1. Prime Factorization Method

Prime factorization involves expressing 200 as a product of prime numbers and then simplifying:

  • First, find the prime factors of 200: \( 200 = 2 \times 2 \times 2 \times 5 \times 5 \).
  • Group the prime factors into pairs: \( 200 = (2 \times 2) \times (5 \times 5) \times 2 \).

  • Simplify to get: \( \sqrt{200} = 10\sqrt{2} \).
  • Using the approximate value of \( \sqrt{2} \approx 1.414 \), we get \( 10 \times 1.414 = 14.14 \).

2. Long Division Method

The long division method provides a systematic way to find the square root of 200:

  1. Write 200 as 200.000000 and pair the digits from the right: [2][00][00][00].
  2. Find the largest integer whose square is less than or equal to 2. Here, it is 1.
  3. Place 1 as the quotient and subtract 1² from 2, leaving a remainder of 1. Bring down the next pair of zeros to get 100.
  4. Double the quotient (1) to get 2 and find a number X such that 20X * X ≤ 100. Here, X is 4, giving 24 * 4 = 96. Subtract 96 from 100 to get a remainder of 4.
  5. Repeat the process with the new dividend 400. Double the current quotient (14) to get 28 and find X such that 280X * X ≤ 400. Here, X is 1, giving 281 * 1 = 281. Subtract to get 119.
  6. Continue this iterative process to get more decimal places, resulting in approximately 14.142.

3. Newton-Raphson Method

The Newton-Raphson method is an iterative numerical approach:

  2. Use the formula: \( \text{next guess} = \frac{1}{2} \left( \text{current guess} + \frac{200}{\text{current guess}} \right) \).
  3. Substitute the initial guess: \( \text{next guess} = \frac{1}{2} \left( 14 + \frac{200}{14} \right) = 14.142857 \).
  4. Repeat the averaging step until the value stabilizes: \( \text{next guess} = \frac{1}{2} \left( 14.142857 + \frac{200}{14.142857} \right) = 14.142136 \).
  5. After a few iterations, the result converges to approximately 14.142.

Numerical Methods (e.g., Newton-Raphson)

The Newton-Raphson method is a powerful numerical technique used to find approximations to the roots of a real-valued function. It is particularly useful for finding square roots. Here's a detailed step-by-step guide to using the Newton-Raphson method to calculate the square root of 200:

  1. Define the function:

    We start with the function \( f(x) = x^2 - 200 \), which we want to find the root of, i.e., the value of \( x \) that makes \( f(x) = 0 \).

  2. Calculate the derivative:

    The derivative of \( f(x) \) is \( f'(x) = 2x \).

  3. Choose an initial guess:

    Select an initial guess \( x_0 \). A good starting point might be \( x_0 = 14 \) because \( 14^2 = 196 \), which is close to 200.

  4. Iterate using the Newton-Raphson formula:

    The Newton-Raphson iteration formula is:

    \[ x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)} \]

    Substituting the functions we get:

    \[ x_{n+1} = x_n - \frac{x_n^2 - 200}{2x_n} \]

  5. Perform iterations:

    • First iteration:
    • \[ x_1 = 14 - \frac{14^2 - 200}{2 \cdot 14} = 14 - \frac{196 - 200}{28} = 14 + 0.142857 = 14.142857 \]

    • Second iteration:
    • \[ x_2 = 14.142857 - \frac{14.142857^2 - 200}{2 \cdot 14.142857} \approx 14.142857 - \frac{200.00205 - 200}{28.285714} \approx 14.142857 - 0.000072 \approx 14.142785 \]

    • Third iteration:
    • \[ x_3 = 14.142785 - \frac{14.142785^2 - 200}{2 \cdot 14.142785} \approx 14.142785 - \frac{200.000001 - 200}{28.28557} \approx 14.142785 - 0.000000035 \approx 14.142785 \]

    After a few iterations, the value converges to approximately 14.142135, which is the square root of 200 to a high degree of accuracy.

This method demonstrates the rapid convergence of the Newton-Raphson method, making it a highly efficient way to compute square roots and other roots of functions.

  • Diagonals of a Rectangle: For a rectangle with a width of 10 units and an unknown height, if the diagonal is 20 units, you can use the Pythagorean theorem to find the height. Using the formula \(d = \sqrt{w^2 + h^2}\), where \(d\) is the diagonal, \(w\) is the width, and \(h\) is the height:

    \[
    20 = \sqrt{10^2 + h^2} \implies 400 = 100 + h^2 \implies h^2 = 300 \implies h = \sqrt{300} = 10\sqrt{3} \approx 17.32 \text{ units}.
    \]

  • Circumference and Area of Circles: If the radius of a circle is \(\sqrt{200}\) units, you can find the circumference and area using the formulas \(C = 2\pi r\) and \(A = \pi r^2\).
