Let us first understand the an interpretation of square root. Thesquare root of a number is the number that,when multiply to itself, gives the product as the original number.

Consider the example:

22= 2× 2is 4

Here 2is referred to as the square source of 4. 4 is a perfect square. Therefore the square root of 4is 2. Non-square numbers likewise have a square root, simply that they space notwhole numbers.For genuine numbers aand b,

a2= ba=√bThis method that ais the second root ofb.

The square source of 4in the radical kind is express as√4and inexponentform, the is expressed together 4½The square source of 4 is the inverse procedure of squaring 2 and also -2

2 × 2 = 4(-2)× (-2) = 4

Is the Square source of 4Rational orIrrational?


A number that have the right to be expressed as a ratio of twointegers, i.e., p/q, q = 0 is called arational number.Now let us look in ~ the square root of 4.√4= 2 = 2/1Thus, √4is a rational number.


How to find the Square source of 4?


There are various ways to calculation the square source of 4. The first method is by prime factorization and also the 2nd is the standard long division method.

Prime Factorization

Let us find the square root of 4using element factorization:

4 = 2× 2√4 = √22√4 = (22)½By the regulation of exponents, considering the strength alone, 2×½ = 1.(22)½= 2√4 = 2

Let united state now shot finding the square source of 4by the long division method!

Square root of 4ByLong Division

Let united state follow the steps to discover the square source of 4by lengthy division.

Step 1: group the digits into pairs (for number to the left of the decimal point, pair castle from best to left) by place a bar end it. Due to the fact that our number is 4, allow us stand for it asinside the department symbol.Step 2: uncover the biggest number together that as soon as you main point it v itself, the product is less than or same to 4. We know that2× 2 is 4and is equal to 4. Currently let united state divide 4by 2
