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

Consider the example:

22= 2× 2is 4

Here 2is called the square root of 4. 4 is a perfect square. For this reason the square source of 4is 2. Non-square numbers likewise have a square root, just 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 type is expressed as√4and inexponentform, it is expressed together 4½The square source of 4 is the inverse procedure of squaring 2 and -2

2 × 2 = 4(-2)× (-2) = 4

Is the Square root of 4Rational orIrrational?


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


How to find the Square source of 4?


There are different ways to calculate the square source of 4. The an initial method is by prime factorization and also the second is the typical long department method.

Prime Factorization

Let us discover the square source of 4using prime factorization:

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

Let united state now try finding the square root of 4by the long department method!

Square source of 4ByLong Division

Let us follow the steps to find the square root of 4by lengthy division.

Step 1: team the digits right into pairs (for digits to the left of the decimal point, pair castle from appropriate to left) by placing a bar over it. Due to the fact that our number is 4, permit us stand for it asinside the division symbol.Step 2: uncover the largest number such that when you multiply it through itself, the product is much less than or equal to 4. We understand that2× 2 is 4and is same to 4. Now let us divide 4by 2
