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 5/9.</p>

4 <h2>What is the Square Root of 5/9?</h2>

5 <p>The<a>square</a>root is the inverse of the square of the<a>number</a>. 5/9 is not a<a>perfect square</a>. The square root of 5/9 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as, √(5/9), whereas (5/9)^(1/2) in the exponential form. √(5/9) = √5/√9 = √5/3, 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 5/9</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 long-<a>division</a>method and approximation method are used. Let us now learn the following methods:</p>

8 <ul><li>Prime factorization method</li>

9 <li>Long division method</li>

10 <li>Approximation method</li>

11 </ul><h2>Square Root of 5/9 by Prime Factorization Method</h2>

12 <p>The prime factorization of 5 is simply 5, as it is a<a>prime number</a>. The prime factorization of 9 is 3 x 3. Now let us look at how 5/9 is broken down:</p>

13 <p><strong>Step 1:</strong>Finding the prime<a>factors</a>of the<a>numerator</a>and the<a>denominator</a>For 5, we have 5 (as it is prime). For 9, we have 3 x 3.</p>

14 <p><strong>Step 2:</strong>The<a>square root</a>of 5/9 is calculated by taking the square root of the numerator and the denominator separately. √(5/9) = √5/√(3 x 3) = √5/3.</p>
