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 fields like vehicle design, finance, etc. Here, we will discuss the square root of 731.</p>

4 <h2>What is the Square Root of 731?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of a<a>number</a>. 731 is not a<a>perfect square</a>. The square root of 731 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √731, whereas in the exponential form it is expressed as (731)¹/². √731 ≈ 27.04163, 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>

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 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 731 by Prime Factorization Method</h2>

12 <p>The<a>product</a>of prime<a>factors</a>is the prime factorization of a number. Now let us look at how 731 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 731 731 is a<a>prime number</a>itself. Hence, the prime factorization of 731 is 731.</p>

14 <p><strong>Step 2:</strong>Since 731 is not a perfect square, calculating the<a>square root</a>using prime factorization directly is not feasible.</p>

34 <h3>Problem 1</h3>

35 <p>Can you help Max find the area of a square box if the side length is given as √731?</p>

36 <p>Okay, lets begin</p>

37 <p>The area of the square is 731 square units.</p>

38 <h3>Explanation</h3>

39 <p>The area of a square = side².</p>

40 <p>The side length is given as √731.</p>

41 <p>Area of the square = (√731) × (√731) = 731.</p>

42 <p>Therefore, the area of the square box is 731 square units.</p>

43 <p>Well explained 👍</p>

44 <h3>Problem 2</h3>

45 <p>A square-shaped land measuring 731 square feet is surveyed; if each of the sides is √731, what will be the square feet of half of the land?</p>

46 <p>Okay, lets begin</p>

47 <p>365.5 square feet</p>

48 <h3>Explanation</h3>

49 <p>We can divide the given area by 2 as the land is square-shaped.</p>

50 <p>Dividing 731 by 2, we get 365.5.</p>

51 <p>So, half of the land measures 365.5 square feet.</p>

52 <p>Well explained 👍</p>
