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 3900.</p>

4 <h2>What is the Square Root of 3900?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. 3900 is not a<a>perfect square</a>. The square root of 3900 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √3900, whereas (3900)^(1/2) in exponential form. √3900 ≈ 62.44998, 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 3900</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 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 3900 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 3900 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 3900 Breaking it down, we get 2 x 2 x 3 x 5 x 5 x 13: 2² x 3¹ x 5² x 13¹</p>

14 <p><strong>Step 2:</strong>Now we found the prime factors of 3900. The second step is to make pairs of those prime factors. Since 3900 is not a perfect square, therefore the digits of the number can’t be grouped in pairs.</p>

15 <p>Therefore, calculating 3900 using prime factorization will yield an approximate value.</p>

20 <p><strong>Step 1:</strong>To begin with, group the numbers from right to left. In the case of 3900, we need to group it as 39 and 00.</p>

19 <p><strong>Step 1:</strong>To begin with, group the numbers from right to left. In the case of 3900, we need to group it as 39 and 00.</p>

21 <p><strong>Step 2:</strong>Find a number whose square is<a>less than</a>or equal to 39. We can say n is ‘6’ because 6 x 6 = 36, which is less than 39. Now the<a>quotient</a>is 6 after subtracting 39 - 36, the<a>remainder</a>is 3.</p>

22 <p><strong>Step 3:</strong>Bring down 00 to make the new<a>dividend</a>300. Add the old<a>divisor</a>with the same number 6 + 6 to get 12, which will be our new divisor.</p>

21 <p><strong>Step 3:</strong>Bring down 00 to make the new<a>dividend</a>300. Add the old<a>divisor</a>with the same number 6 + 6 to get 12, which will be our new divisor.</p>

23 <p><strong>Step 4:</strong>Find a digit n such that 12n x n ≤ 300. Let n be 2. So, 122 x 2 = 244.</p>

22 <p><strong>Step 4:</strong>Find a digit n such that 12n x n ≤ 300. Let n be 2. So, 122 x 2 = 244.</p>

24 <p><strong>Step 5:</strong>Subtract the result from the dividend: 300 - 244 = 56.</p>

23 <p><strong>Step 5:</strong>Subtract the result from the dividend: 300 - 244 = 56.</p>

25 <p><strong>Step 6:</strong>Since the dividend is less than the divisor, add a decimal point. Adding a decimal point allows us to add two zeroes to the dividend. The new dividend is 5600.</p>

24 <p><strong>Step 6:</strong>Since the dividend is less than the divisor, add a decimal point. Adding a decimal point allows us to add two zeroes to the dividend. The new dividend is 5600.</p>

26 <p><strong>Step 7:</strong>Find the new divisor that is 124, because 1244 x 4 = 4976.</p>

25 <p><strong>Step 7:</strong>Find the new divisor that is 124, because 1244 x 4 = 4976.</p>

27 <p><strong>Step 8:</strong>Subtracting 4976 from 5600 gives the result 624.</p>

26 <p><strong>Step 8:</strong>Subtracting 4976 from 5600 gives the result 624.</p>

28 <p><strong>Step 9:</strong>Continue doing these steps until we get two numbers after the decimal point. Suppose if there is no decimal value, continue till the remainder is zero.</p>

36 <h3>Problem 1</h3>

37 <p>Can you help Max calculate the perimeter of a square if its side length is given as √3900?</p>

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

39 <p>The perimeter of the square is approximately 249.8 units.</p>

40 <h3>Explanation</h3>

41 <p>The perimeter of a square = 4 × side length. The side length is given as √3900.</p>

42 <p>Perimeter = 4 × √3900 ≈ 4 × 62.45 = 249.8 units.</p>

43 <p>Therefore, the perimeter of the square is approximately 249.8 units.</p>

44 <p>Well explained 👍</p>

45 <h3>Problem 2</h3>

46 <p>A square-shaped plot measuring 3900 square feet is built; if each of the sides is √3900, what will be the square feet of half of the plot?</p>

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

48 <p>1950 square feet</p>

49 <h3>Explanation</h3>

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

51 <p>Dividing 3900 by 2 gives us 1950.</p>

52 <p>So half of the plot measures 1950 square feet.</p>

53 <p>Well explained 👍</p>

54 <h3>Problem 3</h3>

55 <p>Calculate √3900 × 3.</p>

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

57 <p>187.35</p>

58 <h3>Explanation</h3>

59 <p>The first step is to find the square root of 3900, which is approximately 62.45.</p>

60 <p>The second step is to multiply 62.45 by 3.</p>

61 <p>So 62.45 × 3 = 187.35.</p>

62 <p>Well explained 👍</p>

63 <h3>Problem 4</h3>

64 <p>What will be the square root of (3600 + 300)?</p>

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

66 <p>The square root is approximately 62.45.</p>

67 <h3>Explanation</h3>

68 <p>To find the square root, we need to find the sum of (3600 + 300).</p>

69 <p>3600 + 300 = 3900, and then √3900 ≈ 62.45.</p>

70 <p>Therefore, the square root of (3600 + 300) is approximately ±62.45.</p>

71 <p>Well explained 👍</p>

72 <h3>Problem 5</h3>

73 <p>Find the perimeter of the rectangle if its length ‘l’ is √3900 units and the width ‘w’ is 50 units.</p>

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

75 <p>We find the perimeter of the rectangle as approximately 224.9 units.</p>

76 <h3>Explanation</h3>

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

78 <p>Perimeter = 2 × (√3900 + 50)</p>

79 <p>= 2 × (62.45 + 50)</p>

80 <p>= 2 × 112.45</p>

81 <p>= 224.9 units.</p>
