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 various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 3/7.</p>

4 <h2>What is the Square Root of 3/7?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of a<a>number</a>. The<a>fraction</a>3/7 is not a<a>perfect square</a>. The square root of 3/7 can be expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √(3/7), whereas in the exponential form, it is (3/7)^(1/2). The square root of 3/7 is approximately 0.65465, which is an<a>irrational number</a>because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.</p>

6 <h2>Finding the Square Root of 3/7</h2>

7 <p>For non-perfect squares, methods such as the<a>long division</a>method and approximation method are used to find square roots. 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 3/7 by Long Division Method</h2>

11 <p>The long<a>division</a>method is particularly used for non-perfect squares. In this method, we can find the<a>square root</a>of a fraction by finding the square roots of the<a>numerator and denominator</a>separately.</p>

12 <p><strong>Step 1:</strong>Find the square root of the numerator 3 and the denominator 7 separately using the long division method.</p>

13 <p><strong>Step 2:</strong>The approximate square root of 3 is 1.732, and the square root of 7 is 2.646.</p>

14 <p><strong>Step 3:</strong>Divide the square root of the numerator by the square root of the denominator: 1.732 / 2.646 ≈ 0.65465.</p>

15 <p>So, the square root of 3/7 is approximately 0.65465.</p>

26 <p>The area of the square is approximately 0.428 square units.</p>

28 <h3>Explanation</h3>

27 <h3>Explanation</h3>

29 <p>The area of the square = side^2.</p>

28 <p>The area of the square = side^2.</p>

30 <p>The side length is given as √(3/7).</p>

29 <p>The side length is given as √(3/7).</p>

31 <p>Area of the square = (√(3/7))^2</p>

30 <p>Area of the square = (√(3/7))^2</p>

32 <p>= 3/7</p>

31 <p>= 3/7</p>

33 <p>≈ 0.428.</p>

32 <p>≈ 0.428.</p>

34 <p>Therefore, the area of the square box is approximately 0.428 square units.</p>
