3 <p>If a number is multiplied by itself, the result is a square. The inverse of the square is a square root. The square root is used in fields such as vehicle design, finance, etc. Here, we will discuss the square root of 7700.</p>

4 <h2>What is the Square Root of 7700?</h2>

5 <p>The<a>square</a>root is the inverse of the square of a<a>number</a>. 7700 is not a<a>perfect square</a>. The square root of 7700 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √7700, whereas 7700^(1/2) is the exponential form. √7700 ≈ 87.7496, 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 7700 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 7700 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 7700 Breaking it down, we get 2 x 2 x 5 x 5 x 7 x 11: 2^2 x 5^2 x 7 x 11</p>

14 <p><strong>Step 2:</strong>Now we found the prime factors of 7700. The second step is to make pairs of those prime factors. Since 7700 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating 7700 using prime factorization is not straightforward.</p>

20 <p><strong>Step 2:</strong>Now we need to find n whose square is<a>less than</a>or equal to 77. We can say n is 8 because 8 x 8 = 64, which is less than 77. Now the<a>quotient</a>is 8, and the<a>remainder</a>is 77-64 = 13.</p>

22 <p><strong>Step 4:</strong>Now find the greatest digit x such that 16x x ≤ 1300. The correct digit is 7 because 167 x 7 = 1169, which is less than 1300.</p>

21 <p><strong>Step 4:</strong>Now find the greatest digit x such that 16x x ≤ 1300. The correct digit is 7 because 167 x 7 = 1169, which is less than 1300.</p>

23 <p><strong>Step 5:</strong>Subtract 1169 from 1300; the remainder is 131, and the quotient is 87.</p>

22 <p><strong>Step 5:</strong>Subtract 1169 from 1300; the remainder is 131, and the quotient is 87.</p>

24 <p><strong>Step 6:</strong>Since the dividend is less than the divisor, add a decimal point, allowing us to add two zeroes to the dividend. Now the new dividend is 13100.</p>

32 <h3>Problem 1</h3>

33 <p>Can you help Max find the area of a square box if its side length is given as √7700?</p>

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

35 <p>The area of the square is 7700 square units.</p>

36 <h3>Explanation</h3>

37 <p>The area of the square = side². The side length is given as √7700. Area of the square = side² = (√7700 × √7700) = 7700 square units.</p>

38 <p>Well explained 👍</p>

39 <h3>Problem 2</h3>

40 <p>A square-shaped building measuring 7700 square feet is built; if each of the sides is √7700, what will be the square feet of half of the building?</p>

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

42 <p>3850 square feet</p>

43 <h3>Explanation</h3>

44 <p>We can just divide the given area by 2 as the building is square-shaped. Dividing 7700 by 2 = 3850. So half of the building measures 3850 square feet.</p>

45 <p>Well explained 👍</p>

47 <p>Calculate √7700 × 5.</p>

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

49 <p>438.748</p>

50 <h3>Explanation</h3>

51 <p>The first step is to find the square root of 7700, which is approximately 87.75. The second step is to multiply 87.75 by 5. So 87.75 × 5 = 438.75.</p>

52 <p>Well explained 👍</p>

53 <h3>Problem 4</h3>

54 <p>What will be the square root of (7700 + 100)?</p>

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

56 <p>The square root is approximately 79.87.</p>

57 <h3>Explanation</h3>

58 <p>To find the square root, we need to find the sum of (7700 + 100), which is 7800. The square root of 7800 is approximately 88.32.</p>

61 <p>Find the perimeter of the rectangle if its length ‘l’ is √7700 units and the width ‘w’ is 50 units.</p>

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

63 <p>We find the perimeter of the rectangle as approximately 275.5 units.</p>

64 <h3>Explanation</h3>

65 <p>Perimeter of the rectangle = 2 × (length + width). Perimeter = 2 × (√7700 + 50) ≈ 2 × (87.75 + 50) ≈ 2 × 137.75 ≈ 275.5 units.</p>
