What is the Square Root of 3?
The square root of a number is a number which when multiplied by itself, results in the original number. For example, the square root of 25 is 5, as 5 times 5 results in 25. However, you can also have square roots of some numbers that do not result in whole numbers, such as 3. We can express the square root of 3 in different ways
 Decimal form: 1.732.
 Radical form: √3
 Exponent form: 3^{1/2}
Is the Square Root of 3 Rational or Irrational?
 The decimal part of the square root 3 is nonterminating. This is the definition of an irrational number.
 Looking at the decimal form of the root 3, we see that it is neverending 
√3 = 1.732050807…….  Therefore, we can conclude that Square Root of 3 is Irrational
How to Find the Square Root of 3?
Since we concluded that the square root of 3 is nonterminating, we can only use the longdivision method to calculate its value.
 Step 1: To begin, we write 3 as 3.000000 and group the 0s after the decimal point in pairs of 2 from left to right as shown below. (for digits to the left of the decimal point, pair them from right to left)
 Step 2: Think of a number which when multiplied with itself, is less than or equal to 3. In this case, that number would be 1.
 Step 3: Dividing by 3 by 1 with quotient set as 1, we get a remainder of 2.
 Step 4: Drag a pair of 0’s down and fill it next to 2 to make the dividend 200.
 Step 5: The divisor which is 1 here is added with itself and written below. Now, we have 2X as the new divisor, and we need to find a value of X that makes the product of 2X × X less than or equal to 200. In this case, 27 is the required value
 Step 6: The number 7 is placed in the quotient after a decimal place. The new divisor for the next division will be 2X + X, which is 34 in this case.
Proceeding in the same manner and repeating from step 4, we can calculate the rest of the decimals.

Solved Examples

Example 1
John was wondering whether the value of √3 is the same as √3. What do you think?
Solution
Negative square roots cannot be real numbers.
√3 is a real number.
But √3 is an imaginary number.
Hence, they are not the same, and √3 is not the same as √3. 
Example 2
Micheal is travelling down the highway at an average speed of 50√3 km/hr for exactly 1 hour. How much distance does he cover?
Solution
We need to use the formula Distance = Speed * Time
Speed = 50√3 = 86.603 km/hr
Time = 1 hr
Using the formula, Distance = 86.603 * 1 = 86.603Therefore, Micheal covers a distance of 86.603 km

Example: If the area of a circle is 3π in^{2}. Find the radius of the circle.
Solution:
Let 'r' be the radius of the circle.
⇒ Area of the circle = πr^{2} = 3π in^{2}
⇒ r = ±√3 in
Since radius can't be negative,
⇒ r = √3
The square root of 3 is 1.732.
⇒ r = 1.732 in
FAQs on the Square Root of 3
What is the Value of the Square Root of 3?
The square root of 3 is 1.73205.
Why is the Square Root of 3 an Irrational Number?
The number 3 is prime. This implies that the number 3 is pairless and is not in the power of 2. Therefore, the square root of 3 is irrational.
If the Square Root of 3 is 1.732. Find the Value of the Square Root of 0.03.
Let us represent √0.03 in p/q form i.e. √(3/100) = 0.03/10 = 0.173. Hence, the value of √0.03 = 0.173
Evaluate 14 plus 16 square root 3
The given expression is 14 + 16 √3. We know that the square root of 3 is 1.732. Therefore, 14 + 16 √3 = 14 + 16 × 1.732 = 14 + 27.713 = 41.713
Is the number 3 a Perfect Square?
The number 3 is prime. This implies that the square root of 3 cannot be expressed as a product of two equal integers. Therefore, the number 3 is not a perfect square.
What is the Square Root of 3 in Simplest Radical Form?
The number 3 is a prime number. This implies that the number 3 is pairless and is not in the power of 2. Therefore, the radical form of square root of 3 cannot be simplified further.
