The prime factorization approach is a reliable and straightforward method to simplify the square root of a number. In this section, we will break down the process of simplifying \( \sqrt{50} \) step by step using prime factorization.

1. First, find the prime factors of 50:

   • 50 is an even number, so it is divisible by 2.
   • Divide 50 by 2 to get 25.
   • 25 is not divisible by 2. The next prime number is 3, but 25 is not divisible by 3 either.
   • 25 is divisible by 5. Divide 25 by 5 to get 5.
   • 5 is a prime number, so the prime factorization of 50 is:

   50

   =

   2

   ×

   5

   ×

   5

2. Express \( \sqrt{50} \) using the prime factors:

   \( \sqrt{50} = \sqrt{2 \times 5 \times 5} \)

3. Group the prime factors into pairs:

   \( \sqrt{2 \times 5 \times 5} = \sqrt{2 \times (5 \times 5)} \)

4. Simplify the expression by taking the square root of the paired factors:

   \( \sqrt{2 \times (5 \times 5)} = \sqrt{2} \times \sqrt{5^2} \)

5. Since the square root of \( 5^2 \) is 5, the expression simplifies to:

   \( \sqrt{2} \times 5 \)

6. Finally, write the simplified form:

   \( 5\sqrt{2} \)

Therefore, the simplified form of \( \sqrt{50} \) using the prime factorization approach is \( 5\sqrt{2} \).

To simplify the square root of 50, we can use several techniques that make the process straightforward and easy to understand. Here are the detailed steps:

Prime Factorization Method

This method involves breaking down the number under the square root into its prime factors and simplifying accordingly.

1. First, factorize 50 into its prime factors:

   \( 50 = 2 \times 5 \times 5 \)

2. Rewrite the square root of 50 using these factors:

   \( \sqrt{50} = \sqrt{2 \times 5^2} \)

3. Since the square root of a product is the product of the square roots, simplify by taking the square root of the perfect square (25):

   \( \sqrt{50} = \sqrt{2} \times \sqrt{5^2} \)

   \( \sqrt{50} = \sqrt{2} \times 5 \)

4. Therefore, the simplified form is:

   \( \sqrt{50} = 5\sqrt{2} \)

Using the Properties of Square Roots

The properties of square roots can also be useful in simplification. Specifically, the property \( \sqrt{a \times b} = \sqrt{a} \times \sqrt{b} \) helps to break down complex radicals.

• For example, \( \sqrt{50} = \sqrt{25 \times 2} \)
• Applying the property:

  \( \sqrt{50} = \sqrt{25} \times \sqrt{2} \)

• Since \( \sqrt{25} = 5 \):

  \( \sqrt{50} = 5\sqrt{2} \)

Decimal Form and Estimation

Although the exact simplified form of \( \sqrt{50} \) is \( 5\sqrt{2} \), it can also be useful to know its approximate decimal value, especially for practical applications.

1. We know that \( \sqrt{2} \approx 1.414 \).
2. Multiplying this by 5 gives the decimal approximation:

   \( \sqrt{50} \approx 5 \times 1.414 = 7.07 \)

Summary

In summary, the square root of 50 can be simplified using the prime factorization method or properties of square roots to get \( 5\sqrt{2} \). For practical purposes, the decimal approximation is approximately 7.07.

The square root of a number \( n \) is the value that, when multiplied by itself, gives \( n \). For example, the square root of 25 is 5 because \( 5 \times 5 = 25 \). This is expressed as \( \sqrt{25} = 5 \). The number 50 is not a perfect square, so its square root is not an integer.

To simplify \( \sqrt{50} \), we use the properties of square roots and factorization:

1. First, factor the number 50 into its prime factors:
   • \( 50 = 2 \times 5^2 \)
2. Next, apply the product rule for radicals, which states \( \sqrt{ab} = \sqrt{a} \cdot \sqrt{b} \):
   • \( \sqrt{50} = \sqrt{2 \times 5^2} = \sqrt{2} \cdot \sqrt{5^2} \)
3. Since \( \sqrt{5^2} = 5 \), we can simplify further:
   • \( \sqrt{50} = 5 \cdot \sqrt{2} \)

Therefore, the simplified form of \( \sqrt{50} \) is \( 5\sqrt{2} \).

To verify, we can approximate the values:

• \( \sqrt{50} \approx 7.071 \)
• \( 5\sqrt{2} \approx 5 \times 1.414 = 7.07 \)

The simplified radical form is particularly useful in various mathematical applications, as it often makes further calculations easier and more precise.

The simplification of the square root of 50 to \(5\sqrt{2}\) is a useful mathematical exercise that enhances our understanding of prime factorization and radical expressions. Through the prime factorization method, we decompose 50 into its prime factors, allowing us to simplify the square root by extracting the perfect square factors.

We explored different techniques, including the prime factorization and long division methods, to simplify and approximate the square root of 50. The prime factorization approach involves breaking down 50 into \(2 \times 5^2\) and then simplifying \( \sqrt{50} \) to \( 5\sqrt{2} \). This method illustrates how breaking down numbers into their prime components can simplify the process of finding square roots.

The long division method provides a more precise decimal approximation of the square root of 50, demonstrating the iterative process of refining the value to achieve greater accuracy. This method is particularly useful for non-perfect squares and offers a systematic approach to obtaining decimal values.

Understanding these techniques not only helps in simplifying square roots but also strengthens foundational mathematical skills that are applicable in various advanced topics. By mastering the simplification of square roots, students can build a solid base for tackling more complex mathematical problems and concepts.

In summary, the simplification of \( \sqrt{50} \) to \( 5\sqrt{2} \) exemplifies the power of prime factorization in simplifying radical expressions. This process, combined with the precise long division method, provides a comprehensive understanding of both the exact and approximate values of square roots, reinforcing essential mathematical principles and problem-solving skills.
