Methods to Calculate the Square Root of 266

Calculating the square root of 266 can be approached through various methods, each with its own level of complexity and precision. Here, we'll explore some common techniques, including the Babylonian method, long division method, and using a calculator.

Babylonian Method (Heron's Method)

The Babylonian method, also known as Heron's method, is an iterative technique that starts with an initial guess and refines it to get closer to the actual square root. Here's how it works:

  1. Initial Guess: Choose an initial guess close to the square root. For example, 16.
  2. Iterate: Apply the formula:

    \[
    \text{New guess} = \frac{\text{Old guess} + \frac{266}{\text{Old guess}}}{2}
    \]

    For the initial guess of 16:

    \[
    \text{New guess} = \frac{16 + \frac{266}{16}}{2} \approx 16.3125
    \]

  3. Repeat: Continue the process with the new guess:

    \[
    \text{New guess} = \frac{16.3125 + \frac{266}{16.3125}}{2} \approx 16.308
    \]

  4. Convergence: Repeat until the value stabilizes. The value converges to approximately 16.308.

Long Division Method

The long division method is a manual technique that provides a step-by-step process to find the square root. Here’s a simplified overview:

  1. Pair Digits: Start from the decimal point and pair the digits of the number. For 266, consider it as 2|66.
  2. Initial Divisor: Find the largest number whose square is less than or equal to the first pair (2). The largest number is 1 (since \(1^2 = 1\)).
  3. Subtract and Bring Down: Subtract 1 from 2 and bring down the next pair (66), making it 166.
  4. Double and Estimate: Double the divisor (1 becomes 2) and find a digit that, when added to 20 and multiplied by the same digit, gives a product less than or equal to 166. The digit is 6, since \(26 \times 6 = 156\).
  5. Repeat: Continue the process to achieve the desired precision.

Using a Calculator

For a quick and precise result, a scientific calculator can be used:

  • Step 1: Enter 266.
  • Step 2: Press the square root (√) button.
  • Result: The calculator will display \( \sqrt{266} \approx 16.308 \).

Each method offers a different balance of simplicity, effort, and precision. The Babylonian method is effective for manual calculations with a high degree of accuracy, while the long division method provides a systematic approach for precise manual calculations. Using a calculator is the quickest and most straightforward method for obtaining an accurate result.

    • \( -\frac{2}{3} \) (-0.666...)
  • Properties:
    • Rational numbers can be either positive, negative, or zero.
    • The decimal expansion of a rational number either terminates or repeats periodically.

Irrational Numbers

An irrational number is a number that cannot be expressed as a simple fraction of two integers. The decimal representation of an irrational number is non-terminating and non-repeating. These numbers cannot be written in the form:

\[
\frac{a}{b}
\]
