Methods to Calculate Square Root of 4 with Examples and FAQs



Calculate Square Root

What is a square root?

The square root of a number is the number which, when multiplied to itself, gives the product, which is an original number.

 Let’s take an example

2×2 =4

Here 4 is a perfect square of 2, and the square root of 4 is 2.

The exact value of √4 is 2. Now the roots of √4 can be either positive or negative. Every number has two roots, positive and negative. Thus square root of 4  can be represented as 2 or -2. Thus to conclude, a square root of a number can be presented as ± 2.

 Every number has a square root. For non-square numbers, their square root does not tend to be in whole numbers.

let’s take an example

Square of A = B

A = √B

which means that A is the square root of B.

What do you mean by Perfect Square?

The natural numbers, which are squares of other natural numbers, are known as perfect squares.

The perfect square number has a whole number square root. The square root of 4 is 2, which means that a square root is a whole number, which means that 4 is a perfect square.

For example:

Following is a list of some Perfect square numbers.

Integer                                 Perfect square
2 x 24
3 x 39
4 x 416
5 x 525

Exponential Form & Radical Form

The Radical form of a number is expressed as 


if a number is 4, radical form is √4

The Exponential form of a number is expressed as


If a number is 4, exponential form is 4½

 The square root of a number is Rational or Irrational 

A rational number is expressed as a ratio of two integers as a/b where b is not equal to 0.


√4 =2

which means 2/1 as a/b

Thus the b is not equal to 0. Thus square root of 4 is a rational number.

If the square root of a number is not the whole number, then the square root of a number is an irrational number.

 How to find a square root of 4?

 To calculate the square root of a number, there are two methods:

Prime Factorisation

Long division method

Let’s understand how to calculate the square root of 4 through both the method given.

Prime Factorisation

In prime factorisation methods, we find factors of a number given. Let’s understand it through our example.


If the number is 4, divide 4 into its factors which are

4 = 2×2×1

√4= square of (2)

√4= ( square of 2)½

√4 = 2

which means the square root of 4 is 2.

Long division method

In the Long division method, we place the number inside the division symbol; let’s understand with an example.


If the number is 4,

 Step 1: Try to pair the numbers into pairs by placing a bar over it, i.e. for digits to the left of a decimal point, pair them from right to left.

 Step 2: Since the number is 4, We know that 2× 2 is 4 and equal 4. Now let’s divide 4 by 2. Find the largest number so that when you multiple the number to itself, the product is less than or equal to 4.

 Step 3: After the division of 4 by 2, the remainder is 0, and the quotient is 2. Thus the square root of 4 is 2, and the process of the long division gets completed.

What Are the Physical Characteristics of Land in Real Estate?



Physical Characteristics of Land in Real Estate

The Three Physical Characteristics of Land


We should start with the main attribute of land. The term fixed status land in the housing markets implies that land can’t be moved from a specific spot to another area.

Upgrades and development can be made on it, yet the actual land can’t be moved, and no activity can truly move it.  Online Quran classes for kids

For this reason the area of a land parcel generally affects its cost and request. Local charges can likewise contrast contingent upon where a specific real estate parcel is found.

An illustration of this is the cost of fuel. Fuel bought in a city will cost more than fuel purchased on the edges of an area or neighbourhood.

Somebody can pick where the person gets their fuel. The actual fuel continues as before, yet the cost contrasts relying upon where you get it.

That is the reverse of the land’s worth. Not at all like fuel, land can’t be moved.

In view of this fixed status, the land’s environmental elements, like houses and structures, impact the interest, values, and costs of plots.


One more trait of land is its indestructibility or lastingness. In the housing market, it’s one nature of land which states it can’t be annihilated.

All in all, the worth and presence of land can switch contingent upon the switching conditions around it. Yet, taking everything into account, its size, shape, and strength continue as before.

Hence, property protection doesn’t cover land but instead, covers the upgrades made on it.

On the off chance that a house gets obliterated, the worth of the land it sits on continues as before in light of the fact that it can’t be obliterated. That being said, there are a few examples when land moves.  Learn Pashto online

In any event, when two areas could appear to be identical, the truth is they are as yet exceptional from each other.

Their area, the sort of structures or houses based on them, and their enhancements might contrast. They likewise fluctuate with regards to measure and shape.

For instance, assuming that two packages of property found next to each other may appear to be identical, one of the bundles is nearer to the turnpike than the other.

In light of this, the plot nearer to the expressway has less worth than the package found farther from the road, regardless of whether the possession is something very similar.

Their distinction in area is a decent outline of the uniqueness or heterogeneity of each package.


The actual qualities of land in land are significant illustrations to comprehend how various packages are esteemed, evaluated, and what certain elements and upgrades mean for them.  Quran Tajweed Rules

While there are different qualities, for example, the monetary attributes of land, understanding the actual attributes can help you in your dynamic cycle while buying land
