The square root of 500, represented as \( \sqrt{500} \), is approximately equal to 22.3607. This value is derived from finding the number which, when multiplied by itself, equals 500. For practical purposes, this can be expressed as:

\[ \sqrt{500} \approx 22.3607 \]

Here is a step-by-step breakdown of how to determine the square root of 500:

• First, recognize that 500 is not a perfect square, so its square root will be an irrational number.
• Using the prime factorization method, we can express 500 as \( 2^2 \times 5^3 \).
• Simplify the expression under the square root: \( \sqrt{500} = \sqrt{2^2 \times 5^3} = 10\sqrt{5} \).
• Since \( \sqrt{5} \) is approximately 2.236, multiplying this by 10 gives us 22.36, which can be rounded to 22.3607 for more precision.

Therefore, the value of the square root of 500 in its simplest radical form is \( 10\sqrt{5} \), and in decimal form, it is approximately 22.3607.

The square root of 500 in its simplest radical form is represented as √500. To express this in radical form, we first need to determine its prime factorization.

Let's break down 500 into its prime factors:

• 500 = 2 × 250
• 250 = 2 × 125
• 125 = 5 × 25
• 25 = 5 × 5

Therefore, the prime factorization of 500 is:

500 = 2² × 5³

To simplify the square root, we pair the prime factors:

√500 = √(2² × 5³)

We can take out pairs of prime factors from under the square root:

√500 = √(2²) × √(5² × 5)

This simplifies to:

√500 = 2 × 5√5

Thus, the square root of 500 in radical form is:

√500 = 10√5

There are several methods to calculate the square root of 500. Here are the most common methods:

• Prime Factorization Method

In this method, we factorize 500 into its prime factors:

\(500 = 2^2 \times 5^3\)

To find the square root, we pair the prime factors:

\(\sqrt{500} = \sqrt{(2 \times 2) \times (5 \times 5) \times 5} = 10 \sqrt{5} \approx 22.36\)

• Long Division Method

This method involves the following steps:

1. Start with 500 and pair the digits from right to left, adding decimal places as necessary.
2. Find a number that when squared is less than or equal to 500. This number is 22.
3. Subtract 22 squared (484) from 500, giving a remainder of 16.
4. Bring down pairs of zeros and repeat the division process until the desired precision is achieved.

The result is approximately 22.36067.

• Newton's Method (Iterative)

This is an iterative method starting with an initial guess:

\(x_{n+1} = \frac{1}{2} \left( x_n + \frac{500}{x_n} \right)\)

Starting with \(x_0 = 10\), we iterate to refine the value:

• First iteration: \(x_1 = \frac{1}{2} \left( 10 + \frac{500}{10} \right) = 25\)
• Second iteration: \(x_2 = \frac{1}{2} \left( 25 + \frac{500}{25} \right) = 23\)
• Continue until the value stabilizes around 22.36.
• Using a Calculator

For quick and accurate results, a calculator can be used to find the square root of 500 directly.

Each of these methods provides a way to calculate the square root of 500, with varying levels of complexity and precision.

A perfect square is a number that can be expressed as the product of an integer with itself. For instance, numbers like 1, 4, 9, 16, and 25 are perfect squares because they can be written as 1^2, 2^2, 3^2, 4^2, and 5^2, respectively.

To determine if 500 is a perfect square, we follow these steps:

1. Find the prime factorization of 500: \(500 = 2^2 \times 5^3\).
2. Check the exponents of all prime factors in the factorization. If all the exponents are even, the number is a perfect square.
3. In the factorization of 500, the exponent of 2 is 2 (which is even), but the exponent of 5 is 3 (which is odd).

Since the exponent of 5 is odd, 500 is not a perfect square.

Thus, we can conclude that:

• 500 is not a perfect square because its prime factorization does not have all even exponents.
• Its square root, approximately 22.3607, is not an integer, further confirming that 500 is not a perfect square.

Here's a summary in a table format:

The square root of 500 is an irrational number because it cannot be expressed as a simple fraction. In decimal form, it is approximately 22.3607, where the digits continue indefinitely without repeating.

The square root of 500 as a decimal is approximately 22.3607. It is a non-terminating, non-repeating decimal, meaning its digits continue infinitely without settling into a pattern.

The square root of 500 can be expressed with an exponent as \( 500^{1/2} \).
