7 Square Root Of 2

In Mathematics, the square root of 7 is a number, which is multiplied past itself for two times results in the original number 7. To discover the foursquare root of the given number, we need to know if it is a perfect square or non. Number 7 is non a perfect square. Therefore, we accept to find the square root of 7 using the long division method.In this article, we are going to acquire how to find the value of foursquare root 7 using the long division method with consummate explanation.

What is the Value of Square Root of seven?

The value of foursquare root of seven is a number which when multiplied past itself two times results in the original number. Symbolically, the square root of vii is expressed as √7. In other words, the radical form of foursquare root of 7 is √vii.

√7 = √(Number × Number)

Thus, if nosotros multiply 2.645 two times, we obtain the number seven.

(i.e) √7 = √(2.645×ii.645)

√7 = √(two.645) 2

Now, cancel out square and square root, we go

√7 = ii.645.

Thus, the foursquare root of seven, √7 is approximately equal to ii.645.

Square Root of 7 in Decimal Form: 2. 645

Square Root of 7 by Long Division Method

Since the number seven is not a perfect square number, the foursquare root of 7 is found using the long partitioning method. Now, follow the below steps to find the value of √vii.

First, write the number 7 in decimal class. (i.e) 7. 0000
At present, carve up the number seven by a number such the product of aforementioned number should be smaller than or equal to 7. Thus, 2×ii = 4, which is smaller than 7.
Now, subtract 4 from 7, nosotros will get the residual 3 and caliber ii.
At present, double the quotient and we get four and assume that 40 is the new divisor.
Bring down 2 zeros and we get 300 is our new dividend.
Now, find the number, such that (40+ new number)×new number should exist less than or equal to 300. Hence, (xl+6)×half-dozen = 276. Hence, 276 < 300.
Once again, subtract 276 from 300. Hence, we go a remainder of 24 and the caliber is 26.
Repeat this same process until nosotros get the value of square root of vii up to 3 decimal places. (Put the decimal bespeak in the quotient in one case the division process is completed).
Thus, the value of foursquare root of 7 is approximately equal to ii.645.

Examples

Example one:

Simplify the expression: 2√7 + 5√7.

Solution:

Given: 2√7 + 5√vii.

2√7+5√7 = 7√7.

Nosotros know that √7 is approximately equal to 2.645.

Now, substitute the value, we get

2√seven+5√7 = 7(2.645) = 18.515.

Example 2:

Notice the value of a is a√7= seven.935.

Solution:

Given: a√7= 7.935

Thus, a = 7.935/√vii

a = 7.935/2.645 [Since, √7 = ii.645]

a = 3

Hence, the value of a is iii.
