Square Root of 200 + Solution With Free Steps

Square Root Of 200

The square root of a number is the value, that when squared, gives the required number. For example, the square root of 4 is 2 which is calculated by taking the square of two that is 22=4. A square root is denoted by the symbol √. Hence, the square root of 200 will be expressed as √200.

In this article, we will analyze and find the square root of 200 using various mathematical techniques, such as the approximation method and the long division method.

What Is the Square Root Of 200?

The square root of the number 200 is 14.14.

The square root can be defined as the quantity that can be doubled to produce the square of that similar quantity. In simple words, it can be explained as:

√200 = √(14.14 x 14.14)

√200 = √(14.14)$^2$

√200 = ±14.14

The square can be canceled with the square root as it is equivalent to 1/2; therefore, obtaining 14.14. Hence 14.14 is 200’s square root. The square root generates both positive and negative integers.

How To Calculate the Square Root of 200?

You can calculate the square root of 200 using any of two vastly used techniques in mathematics; one is the Approximation technique, and the other is the Long Division method.

The symbol √ is interpreted as 200 raised to the power 1/2. So any number, when multiplied by itself, produces its square, and when the square root of any squared number is taken, it produces the actual number.

Let us discuss each of them to understand the concepts better.

Square Root by Long Division Method

The process of long division is one of the most common methods used to find the square roots of a given number. It is easy to comprehend and provides more reliable and accurate answers. The long division method reduces a multi-digit number to its equal parts.

Learning how to find the square root of a number is easy with the long division method. All you need are five primary operations- divide, multiply, subtract, bring down or raise, then repeat.

Following are the simple steps that must be followed to find the square root of 200 using the long division method:

Step 1

First, write the given number 200 in the division symbol, as shown in figure 1.

Step 2

Starting from the right side of the number, divide the number 200 into pairs such as 00 and 2.

Step 3

Now divide the digit a by a number, giving a number either 2 or less than 2. Therefore, in this case, the remainder is 1, whereas the quotient is one.

Step 4

After this, bring down the next pair 00. Now the dividend is 00. To find the next divisor, we need to double our quotient obtained before. Doubling 1 gives 2; hence consider it as the next divisor.

Step 5

Now pair 2 with another number to make a new divisor that results in $\leq$ 100 when multiplied with the divisor. If the number is not a perfect square, add pair of zeros to the right of the number before starting division.

Step 6

Adding 4 to the divisor and multiplying 24 with 4 results in 96 $\leq$ 100. The remainder obtained is 4. Move the next pair of zeros down and repeat the same process mentioned above.

Step 7

Keep on repeating the same steps till the zero remainder is obtained or if the division process continues infinitely, solve to two decimal places.

Step 8

The resulting quotient of 14.14 is the square root of 200. Figure 1 given below shows the long division process in detail:

Square Root by Approximation Method

The approximation method involves guessing the square root of the non-perfect square number by dividing it by the perfect square lesser or greater than that number and taking the average.

The given detailed steps must be followed to find the square root of 200 using the approximation technique.

Step 1

Consider a perfect square number 196 less than 200.

Step 2

Now divide 200 by √196.

200 ÷ 14 = 14.286

Step 3

Now take the average of 14 and 14.286. The resulting number is approximately equivalent to the square root of 200.

(14 + 14.286) ÷ 2 = 14.14

Important points

  • The number 200 is a perfect square/ not a perfect square.
  • The number 200 is a rational number/ irrational number.
  • The number 200 can be split into its prime factorization.

Is Square Root of 200 a Perfect Square?

The number 200 is not a perfect square. A number is a perfect square if it splits into two equal parts or identical whole numbers. If a number is a perfect square, it is also rational.

A number expressed in p/q form is called a rational number. All the natural numbers are rational. A square root of a perfect square is a whole number; therefore, a perfect square is a rational number.

A number that is not a perfect square is irrational as it is a decimal number. As far as 200 is concerned, it is not a perfect square. It can be proved as below:

Factorization of 200 results in 4 x 50.

Taking the square root of the above expression gives:

= √(4 x 50)

= (4 x 50)$^{1/2}$

= 14.14

This shows that 200 is not a perfect square as it has decimal places; hence it is an irrational number.

Therefore the above discussion proves that the square root of 200 is equivalent to 14.14.
