Square Root 200 Simplified: A Comprehensive Guide

The square root of 200 can be simplified by using prime factorization. Below are the detailed steps and methods to simplify the square root of 200.

Prime Factorization Method

Prime factorization involves expressing a number as a product of its prime factors. For 200, the prime factors are:

\[ 200 = 2 \times 2 \times 2 \times 5 \times 5 \]

Grouping the factors in pairs gives us:

\[ 200 = (2^2) \times (5^2) \times 2 \]

Taking the square root of each pair of factors and multiplying the results, we get:

\[ \sqrt{200} = \sqrt{(2^2) \times (5^2) \times 2} = 2 \times 5 \times \sqrt{2} = 10\sqrt{2} \]

Therefore, the simplified form of the square root of 200 is:

\[ \sqrt{200} = 10\sqrt{2} \]

Long Division Method

The long division method is another way to find the square root of 200. Here are the steps:

1. Pair up the digits of 200 from right to left, giving us 2 | 00. Start with the first pair.
2. Find a number which, when squared, is less than or equal to 2. The closest number is 1 (since \( 1^2 = 1 \)). Subtract 1 from 2, leaving a remainder of 1. Bring down the next pair of zeros, making the new dividend 100.
3. Double the quotient (1) to get 2. Determine the largest digit (X) such that \( 2X \times X \) is less than or equal to 100. The digit is 4, since \( 24 \times 4 = 96 \). Subtract 96 from 100 to get a remainder of 4. Bring down the next pair of zeros, making it 400.
4. Repeat the process to get more decimal places.

Following these steps, we find that:

\[ \sqrt{200} \approx 14.142 \]

Square Root in Decimal Form

The square root of 200 is an irrational number and can be represented in decimal form as approximately:

The square root of 200 is an important concept in mathematics, often used in various calculations and applications. It involves finding a number which, when multiplied by itself, gives the original number 200. The square root of 200 is an irrational number and cannot be expressed as a simple fraction. It can be simplified and expressed in various forms, including radical and decimal forms.

The square root of 200 in its simplest radical form is:

• Radical Form: \( \sqrt{200} = 10\sqrt{2} \)

In decimal form, the square root of 200 is approximately:

• Decimal Form: \( \sqrt{200} \approx 14.142 \)

We can determine the square root of 200 using two common methods: the prime factorization method and the long division method.

Prime Factorization Method

Using the prime factorization method, we break down 200 into its prime factors:

• Prime Factorization: \( 200 = 2 \times 2 \times 2 \times 5 \times 5 \)

Then, we pair the prime factors:

• Pairing: \( \sqrt{200} = \sqrt{(2^2) \times 2 \times (5^2)} = 2 \times 5 \times \sqrt{2} = 10\sqrt{2} \)

Long Division Method

The long division method involves the following steps:

1. Write 200 as 200.000000 and pair the digits from the right.
2. Find the largest number whose square is less than or equal to 2, which is 1. Subtract 1 from 2, bringing down a pair of zeros to get 100.
3. Double the divisor (1) to get 2. Find a number that, when added to 20 and multiplied by itself, gives a product less than or equal to 100. This number is 4.
4. Subtract 96 (24 × 4) from 100 to get a remainder of 4. Repeat the process to get more decimal places.

This method yields an approximation of the square root of 200:

• Long Division Result: \( \sqrt{200} \approx 14.142 \)

Thus, understanding and calculating the square root of 200 using these methods can be helpful in solving various mathematical problems efficiently.

To express the square root of 200 in its simplest radical form, we start by performing the prime factorization of 200.

• First, we identify the prime factors of 200: 200 = 2 × 2 × 2 × 5 × 5.
• Next, we group the prime factors into pairs: 200 = (2 × 2) × (5 × 5) × 2.
• Taking the square root of each pair, we get: √(2 × 2) × √(5 × 5) × √2 = 2 × 5 × √2.
• Thus, the simplified form is: 10√2.

In conclusion, the square root of 200, when simplified, is 10√2.

The long division method is a systematic approach to find the square root of 200. Below are the detailed steps to perform the calculation:

1. Start by writing the number 200 as 200.000000 and pair the digits from the right. We have the pairs 2 and 00.
2. Find a number which when squared gives a result less than or equal to 2. This number is 1 (since 1² = 1). Subtract 1 from 2, giving a remainder of 1, and bring down the next pair of zeros, making the new dividend 100.
3. Double the current quotient (which is 1), resulting in 2. Determine the largest digit (let's call it X) that can be placed next to 2, such that 2X * X is less than or equal to 100. Here, X is 4, since 24 * 4 = 96. Subtract 96 from 100, resulting in a remainder of 4, and bring down the next pair of zeros to get 400.
4. Repeat the process: double the current quotient (14), giving 28. Determine the largest digit (Y) to place next to 28 such that 28Y * Y is less than or equal to 400. Y is 1, since 281 * 1 = 281. Subtract 281 from 400 to get a remainder of 119, and bring down the next pair of zeros to get 11900.
5. Continue this process to find further decimal places, if needed. The square root of 200 is approximately 14.142.

Thus, the value of √200 calculated using the long division method is approximately 14.142.

To find the decimal form of the square root of 200, we can use a calculator or apply the long division method. The square root of 200 is an irrational number, meaning it cannot be expressed as a simple fraction and its decimal form is non-repeating and non-terminating.

The approximate decimal form of the square root of 200 is:

\[

\]

Here's a step-by-step explanation using the long division method to find the decimal form of the square root of 200:

1. Pair the digits of 200 from right to left: 200.00

2. Find the largest number whose square is less than or equal to 2. This number is 1 (since 1² = 1).

3. Subtract 1 from 2 to get the remainder: 2 - 1 = 1.

4. Bring down the next pair of zeros, making the new dividend 100.

5. Double the current quotient (1) to get 2, and find a digit X such that 2X * X is less than or equal to 100. X is 4, as 24 * 4 = 96.

6. Subtract 96 from 100 to get the remainder: 100 - 96 = 4.

7. Bring down the next pair of zeros, making the new dividend 400.

8. Double the current quotient (14) to get 28, and find a digit X such that 28X * X is less than or equal to 400. X is 1, as 281 * 1 = 281.

9. Subtract 281 from 400 to get the remainder: 400 - 281 = 119.

10. Continue this process to get more decimal places.

Continuing this process, we can find more decimal places of the square root of 200. Using a calculator or computer, we find:
