3 <p>If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in the field of vehicle design, finance, etc. Here, we will discuss the square root of 3.13.</p>

4 <h2>What is the Square Root of 3.13?</h2>

5 <p>The<a>square</a>root is the inverse of the square of the<a>number</a>. 3.13 is not a<a>perfect square</a>. The square root of 3.13 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √3.13, whereas (3.13)^(1/2) in the exponential form. √3.13 ≈ 1.76918, which is an<a>irrational number</a>because it cannot be expressed in the form of p/q, where p and q are<a>integers</a>and q ≠ 0.</p>

6 <h2>Finding the Square Root of 3.13</h2>

7 <p>The<a>prime factorization</a>method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where the<a>long division</a>method and approximation method are used. Let us now learn the following methods:</p>

8 <ul><li>Long division method</li>

9 <li>Approximation method</li>

10 </ul><h2>Square Root of 3.13 by Long Division Method</h2>

11 <p>The long<a>division</a>method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the<a>square root</a>using the long division method, step by step.</p>

12 <p><strong>Step 1:</strong>To begin with, pair the digits of the number from the<a>decimal</a>point. In the case of 3.13, we consider 3.13 as 3.130000 to make pairing easier.</p>

13 <p><strong>Step 2:</strong>Now we need to find n whose square is<a>less than</a>or equal to 3. We can say n as ‘1’ because 1 × 1 = 1, which is less than 3. Now the<a>quotient</a>is 1, and after subtracting 1 from 3, the<a>remainder</a>is 2.</p>

14 <p><strong>Step 3:</strong>Bring down 13, making the<a>dividend</a>213. Double the quotient (1), and write it as 2. Now we need to find a digit x such that 2x * x is less than or equal to 213.</p>

15 <p><strong>Step 4:</strong>Determine x. In this case, 26 × 6 = 156, which is less than 213. Subtract 156 from 213 to get the remainder 57.</p>

16 <p><strong>Step 5:</strong>Bring down two zeros, making it 5700. Double the quotient (16) to get 32.</p>

17 <p><strong>Step 6:</strong>Find the next digit. 321 × 1 = 321, which is less than 5700. Subtract to get the remainder 2379.</p>

18 <p><strong>Step 7:</strong>Continue this process until you reach the desired level of precision.</p>

19 <p>The square root of 3.13 is approximately 1.76918.</p>
