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 engineering, statistics, etc. Here, we will discuss the square root of 3842.</p>

4 <h2>What is the Square Root of 3842?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of a<a>number</a>. 3842 is not a<a>perfect square</a>. The square root of 3842 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √3842, whereas (3842)^(1/2) in the exponential form. √3842 ≈ 61.9935, 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 long-<a>division</a>and approximation methods 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 3842 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 3842 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 3842 Breaking it down, we find 3842 = 2 x 1921, and 1921 is 13 x 13 x 11.</p>

14 <p><strong>Step 2:</strong>Now we found out the prime factors of 3842. Since 3842 is not a perfect square, the digits of the number can't be grouped in pairs.</p>

15 <p>Therefore, calculating 3842 using prime factorization is not straightforward.</p>

21 <p><strong>Step 2:</strong>Now we need to find n whose square is<a>less than</a>or equal to 38. We can say n as ‘6’ because 6 x 6 = 36, which is less than 38. Now the<a>quotient</a>is 6, and after subtracting 36 from 38, the<a>remainder</a>is 2.</p>

35 <h3>Problem 1</h3>

36 <p>Can you help Max find the area of a square box if its side length is given as √3842?</p>

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

38 <p>The area of the square is approximately 147,533 square units.</p>

39 <h3>Explanation</h3>

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

41 <p>The side length is given as √3842.</p>

42 <p>Area of the square = side^2 = √3842 x √3842 ≈ 61.9935 x 61.9935 ≈ 147,533.</p>

43 <p>Therefore, the area of the square box is approximately 147,533 square units.</p>

45 <h3>Problem 2</h3>

46 <p>A square-shaped building measuring 3842 square feet is built; if each of the sides is √3842, what will be the square feet of half of the building?</p>

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

48 <p>1921 square feet</p>

49 <h3>Explanation</h3>

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

51 <p>Dividing 3842 by 2, we get 1921.</p>

52 <p>So half of the building measures 1921 square feet.</p>

53 <p>Well explained 👍</p>

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

75 <p>The perimeter of the rectangle is approximately 223.987 units.</p>

76 <h3>Explanation</h3>

77 <p>Perimeter of the rectangle = 2 × (length + width).</p>

78 <p>Perimeter = 2 × (√3842 + 50)</p>

79 <p>≈ 2 × (61.9935 + 50)</p>

80 <p>≈ 2 × 111.9935</p>
