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 7/9.</p>

4 <h2>What is the Square Root of 7/9?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. The number 7/9 is not a<a>perfect square</a>. The square root of 7/9 is expressed in both radical and<a>exponential form</a>. In radical form, it is expressed as √(7/9), whereas (7/9)^(1/2) in exponential form. √(7/9) = √7/√9 = √7/3, 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 7/9</h2>

7 <p>The<a>prime factorization</a>method is typically used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers; instead, methods like simplification and approximation are employed. Let us now learn the following methods:</p>

8 <ul><li>Simplification method</li>

9 <li>Approximation method</li>

10 </ul><h2>Square Root of 7/9 by Simplification Method</h2>

11 <p>The simplification method involves expressing the<a>fraction</a>as a<a>product</a>of its individual square roots.</p>

12 <p><strong>Step 1:</strong>Express the fraction as individual square roots. √(7/9) = √7/√9</p>

13 <p><strong>Step 2:</strong>Simplify the<a>square root</a>of the<a>denominator</a>. Since √9 = 3, we have √(7/9) = √7/3</p>

14 <p><strong>Step 3:</strong>The value √7 remains under the square root as it is not a perfect square.</p>

15 <p>Therefore, the simplified form of √(7/9) is √7/3.</p>
