The square root of a fraction, such as 1/9, can be found by taking the square root of the numerator and the square root of the denominator separately. This property of square roots allows us to simplify the expression step by step.

Here's how to simplify the square root of 1/9:

1. Identify the numerator and the denominator of the fraction. In this case, the numerator is 1 and the denominator is 9.
2. Take the square root of the numerator: \(\sqrt{1} = 1\).
3. Take the square root of the denominator: \(\sqrt{9} = 3\).
4. Combine the results to get the simplified form: \(\frac{1}{3}\).

Thus, the square root of \(\frac{1}{9}\) is \(\frac{1}{3}\).

Understanding how to simplify square roots is a fundamental skill in algebra that helps in solving various mathematical problems. The square root of 1/9 being 1/3 demonstrates the simplicity and elegance of working with fractional square roots.

To find the square root of \(\frac{1}{9}\), follow these steps:

1. Recognize that the square root of a fraction can be expressed as the fraction of the square roots of the numerator and the denominator. Mathematically, this can be written as:

   \[ \sqrt{\frac{1}{9}} = \frac{\sqrt{1}}{\sqrt{9}} \]

2. Find the square root of the numerator and the denominator separately:

   • The square root of 1 is 1: \[ \sqrt{1} = 1 \]
   • The square root of 9 is 3: \[ \sqrt{9} = 3 \]

3. Combine these results to get the final answer:

   \[ \sqrt{\frac{1}{9}} = \frac{1}{3} \]

Thus, the square root of \(\frac{1}{9}\) is \(\frac{1}{3}\). This process simplifies the problem step by step, ensuring a clear and accurate result.

The process of simplifying the square root of 1/9 involves several steps to break down the expression and understand its components. Here is a detailed, step-by-step explanation:

1. Identify the expression: The expression we need to simplify is \( \sqrt{\frac{1}{9}} \).
2. Separate the square root: Using the property of square roots, we can separate the numerator and the denominator under the square root: \[ \sqrt{\frac{1}{9}} = \frac{\sqrt{1}}{\sqrt{9}} \]
3. Simplify the numerator and denominator: We know that the square root of 1 is 1, and the square root of 9 is 3. Therefore: \[ \sqrt{1} = 1 \quad \text{and} \quad \sqrt{9} = 3 \]
4. Combine the results: Putting the simplified numerator and denominator together, we get: \[ \frac{1}{3} \]
5. Conclusion: The square root of 1/9 simplifies to 1/3.

This step-by-step simplification shows how to handle square roots involving fractions, making it clear and easy to understand.

Understanding the square root of \(\frac{1}{9}\) involves various related calculations that provide deeper insights into square roots and their properties. Here are detailed steps and examples:

• Basic Square Root Calculation: The square root of \(\frac{1}{9}\) is calculated as follows:

  
  
  \[
  \sqrt{\frac{1}{9}} = \frac{\sqrt{1}}{\sqrt{9}} = \frac{1}{3}
  \]
  

• Square Root of Fractions: The process of finding the square root of a fraction \(\frac{a}{b}\) involves taking the square root of the numerator and the denominator separately:

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

• Perfect Squares: When both the numerator and denominator are perfect squares, their square roots are integers. For example:

  
  
  \[
  \sqrt{\frac{4}{25}} = \frac{2}{5}
  \]
  

• Approximations: For non-perfect squares, approximate methods such as using a calculator can be employed:

  
  
  \[
  \sqrt{2} \approx 1.414 \quad \text{and} \quad \sqrt{3} \approx 1.732
  \]
  

• Negative Numbers: The square root of a negative number involves imaginary numbers, denoted by \(i\) where \(i = \sqrt{-1}\):

  
  
  \[
  \sqrt{-9} = 3i
  \]
  

• Square Roots of Decimals: Finding the square root of decimals follows the same principles, but often results in irrational numbers:

  
  
  \[
  \sqrt{0.25} = 0.5 \quad \text{and} \quad \sqrt{2} \approx 1.414
  \]
