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 7800.</p>

4 <h2>What is the Square Root of 7800?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. 7800 is not a<a>perfect square</a>. The square root of 7800 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √7800, whereas (7800)^(1/2) in the exponential form. √7800 ≈ 88.313, 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 7800</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 7800 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 7800 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 7800 Breaking it down, we get 2 x 2 x 2 x 3 x 5 x 5 x 13: 2^3 x 3^1 x 5^2 x 13^1</p>

14 <p><strong>Step 2:</strong>Now we found the prime factors of 7800. The second step is to make pairs of those prime factors. Since 7800 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating √7800 using prime factorization is impossible.</p>

20 <p><strong>Step 2:</strong>Now we need to find n whose square is close to 78. We can say n is ‘8’ because 8 x 8 = 64, which is<a>less than</a>78. Now the<a>quotient</a>is 8, after subtracting 78 - 64, the<a>remainder</a>is 14.</p>

21 <p><strong>Step 3:</strong>Now bring down 00, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number, 8 + 8, we get 16, which will be our new divisor.</p>

22 <p><strong>Step 5:</strong>The next step is finding 16n x n ≤ 1400. Let us consider n as 8, now 168 x 8 = 1344.</p>

24 <p><strong>Step 6:</strong>Subtract 1344 from 1400. The difference is 56, and the quotient is 88.</p>

23 <p><strong>Step 6:</strong>Subtract 1344 from 1400. The difference is 56, and the quotient is 88.</p>

25 <p><strong>Step 7:</strong>Since the dividend is less than the divisor, we need to add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 5600.</p>

25 <p><strong>Step 8:</strong>Now we need to find the new divisor, which is 176, because 1763 x 3 = 5289.</p>

27 <p><strong>Step 9:</strong>Subtracting 5289 from 5600, we get the result 311.</p>

36 <h3>Problem 1</h3>

37 <p>Can you help Max find the area of a square box if its side length is given as √7800?</p>

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

39 <p>The area of the square is 7800 square units.</p>

40 <h3>Explanation</h3>

41 <p>The area of the square = side^2. The side length is given as √7800. Area of the square = side^2 = √7800 x √7800 = 7800. Therefore, the area of the square box is 7800 square units.</p>

42 <p>Well explained 👍</p>

43 <h3>Problem 2</h3>

44 <p>A square-shaped building measuring 7800 square feet is built; if each of the sides is √7800, what will be the square feet of half of the building?</p>

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

46 <p>3900 square feet</p>

47 <h3>Explanation</h3>

48 <p>We can just divide the given area by 2 as the building is square-shaped. Dividing 7800 by 2 = we get 3900. So half of the building measures 3900 square feet.</p>

49 <p>Well explained 👍</p>

50 <h3>Problem 3</h3>

51 <p>Calculate √7800 x 5.</p>

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

53 <p>441.565</p>

54 <h3>Explanation</h3>

55 <p>The first step is to find the square root of 7800, which is approximately 88.313. The second step is to multiply 88.313 by 5. So 88.313 x 5 = 441.565.</p>

58 <p>What will be the square root of (7800 + 200)?</p>

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

60 <p>The square root is approximately 90.</p>

61 <h3>Explanation</h3>

62 <p>To find the square root, we need to find the sum of (7800 + 200). 7800 + 200 = 8000, and then √8000 ≈ 89.44. Therefore, the square root of (7800 + 200) is approximately 89.44.</p>

64 <h3>Problem 5</h3>

65 <p>Find the perimeter of the rectangle if its length ‘l’ is √7800 units and the width ‘w’ is 50 units.</p>

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

67 <p>We find the perimeter of the rectangle as 276.626 units.</p>

68 <h3>Explanation</h3>

69 <p>Perimeter of the rectangle = 2 × (length + width). Perimeter = 2 × (√7800 + 50) = 2 × (88.313 + 50) = 2 × 138.313 = 276.626 units.</p>
