3 <p>If a number is multiplied by itself, the result is a square. The inverse operation is finding the square root. The square root is used in various fields like vehicle design, finance, etc. Here, we will discuss the square root of 27/4.</p>

4 <h2>What is the Square Root of 27/4?</h2>

5 <p>The<a>square</a>root is the inverse of the square of the<a>number</a>. 27/4 is not a<a>perfect square</a>. The square root of 27/4 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √(27/4), whereas in the exponential form it is expressed as (27/4)^(1/2). √(27/4) = √27/2 = 2.59808, 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 27/4</h2>

7 <p>The<a>prime factorization</a>method is used for perfect square numbers. However, for non-perfect square numbers like 27/4, the long-<a>division</a>and approximation methods 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 27/4 by Long Division Method</h2>

11 <p>The<a>long division</a>method is particularly used for non-perfect square numbers. Let us now learn how to find the<a>square root</a>of 27/4 using the long division method, step by step.</p>

12 <p><strong>Step 1:</strong>First, express the number as a<a>decimal</a>. 27/4 = 6.75.</p>

13 <p><strong>Step 2:</strong>Group the digits from right to left as 6.75.</p>

14 <p><strong>Step 3:</strong>Find n whose square is closest to 6. The closest is 2, because 2² = 4.</p>

15 <p><strong>Step 4:</strong>Subtract 4 from 6, bringing down 75 to get 275.</p>

16 <p><strong>Step 5:</strong>Double the<a>quotient</a>obtained, which is 2, to get 4 and find a digit x such that 4x × x ≤ 275. The suitable x is 5, as 45 × 5 = 225.</p>

17 <p><strong>Step 6:</strong>Subtract 225 from 275 to get 50.</p>

18 <p><strong>Step 7:</strong>Add a decimal point and bring down 00 to make it 5000.</p>

19 <p><strong>Step 8:</strong>Double the quotient 25 to get 50, then find x such that 50x × x ≤ 5000. The suitable x is 9, as 509 × 9 = 4581.</p>

20 <p><strong>Step 9:</strong>Subtract 4581 from 5000 to get 419.</p>

21 <p><strong>Step 10:</strong>Continue this process to get more decimal places.</p>

22 <p>The square root of 6.75 is approximately 2.59808.</p>

25 <p>The approximation method is another method for finding square roots. Let us learn how to find the square root of 27/4 using the approximation method.</p>

27 <p><strong>Step 1:</strong>Find the closest perfect squares around 27/4. The smallest perfect square is 4 and the largest perfect square is 9. √(27/4) lies between √4 = 2 and √9 = 3.</p>

26 <p><strong>Step 1:</strong>Find the closest perfect squares around 27/4. The smallest perfect square is 4 and the largest perfect square is 9. √(27/4) lies between √4 = 2 and √9 = 3.</p>

28 <p><strong>Step 2:</strong>Apply the<a>formula</a>(Given number - smallest perfect square)/(Greater perfect square - smallest perfect square). Using the formula, (6.75 - 4)/(9 - 4) = 0.55.</p>

27 <p><strong>Step 2:</strong>Apply the<a>formula</a>(Given number - smallest perfect square)/(Greater perfect square - smallest perfect square). Using the formula, (6.75 - 4)/(9 - 4) = 0.55.</p>

29 <p><strong>Step 3:</strong>Add this decimal to the smaller root: 2 + 0.55 = 2.55. Adjust further by checking higher precision to approximate further.</p>

28 <p><strong>Step 3:</strong>Add this decimal to the smaller root: 2 + 0.55 = 2.55. Adjust further by checking higher precision to approximate further.</p>

30 <p>Thus, the square root of 6.75 is approximately 2.59808.</p>

29 <p>Thus, the square root of 6.75 is approximately 2.59808.</p>
