# Square Root of 800 + Solution With Free Steps

This article provides an easy and detailed solution to the square root of a three-digit number. The square root of 800, which is represented as **âˆš800, **is equivalent to** 28.28. **Elaborated steps to determine the square root of 800 are provided in the following paragraphs.

In this article, we will analyze and find the **square root of 800**Â using various mathematical techniques, such as the approximation method and the long division method.

## What Is the Square Root Of 800?

**The square root of the number 800 is 28.28.**

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:

**âˆš800 = âˆš(28.28 x 28.28)**

**âˆš800 = âˆš(28.28)$^2$**

**âˆš800 = Â±28.28**

The square can be canceled with the square root as it is **equivalent to 1/2**; therefore, obtaining 28.28. Hence 28.28 is 800’s square root. The square root generates both **positive** and **negative integers**.

## How To Calculate the Square Root of 800?

You can calculate the **square root of 800**Â using any of two vastly used techniques in mathematics; one is the **Approximation technique**, and the other is the **Long Division method**.

The symbolÂ **âˆšÂ **is interpreted asÂ **800**Â raised to the power**Â 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 of 800 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 **800 **using the long division method:

### Step 1

First, write the given number** 800 **in the division symbol, as shown in figure 1.

### Step 2

Starting from the right side of the number, divide the number 800 into **pairs** such as 00 and 8.

### Step 3

Now divide the digit 8 by a number, giving a number either 8 or less than 8. Therefore, in this case, the remainder is 4, whereas the quotient is 2.

### Step 4

After this, bring down the next pair 00. Now the **dividend** is 400. To find the next divisor, we need to double our quotient obtained before. Doubling 2 gives 4; hence consider it as the next divisor.

### Step 5

Now pair 4 with another number to make a new divisor that results in $\leq$ 400 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 8 to the divisor and multiplying 48 with 8 results in 384 $\leq$ 400. The remainder obtained is 16. 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 28.28 is the square root of 800. 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 800**Â using the approximation technique.

### Step 1

Consider a perfect square number 784 less than 800.

### Step 2

Now divide 800 by 28.

**800 Ã· 28 = 28.57**

### Step 3

Now take the average of 28 and 28.57. The resulting number is approximately equivalent to the square root of 800.

**(28 + 28.57) Ã· 2 = 28.28**

### Important points

- The number 800 is not a perfect square.
- The number 800 is an irrational number.
- The number 800 can be split into its prime factorization.

## Is Square Root of 800 a Perfect Square?

The number 800 is**Â 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 800 is concerned, it is not a perfect square. It can be proved as below:

Factorization of 800 results in 4 x 200.

Taking the square root of the above expression gives:

**= âˆš(4 x 200)**

**= (4 x 200)$^{1/2}$**

**= 28.28**

This shows that 800 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 800 is equivalent to 28.28.
