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 such as vehicle design, finance, etc. Here, we will discuss the square root of 1280.</p>

4 <h2>What is the Square Root of 1280?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. 1280 is not a<a>perfect square</a>. The square root of 1280 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √1280, whereas (1280)^(1/2) in the exponential form. √1280 ≈ 35.7771, 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 1280</h2>

7 <p>The<a>prime factorization</a>method is used for perfect square numbers. However, for non-perfect square numbers, the prime factorization method is not used; instead, 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 1280 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 1280 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 1280. Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5: 2^7 x 5^2.</p>

14 <p><strong>Step 2:</strong>Now we found out the prime factors of 1280. The second step is to make pairs of those prime factors. Since 1280 is not a perfect square, therefore the digits of the number can’t be grouped in pairs perfectly.</p>

15 <p>Therefore, calculating √1280 using prime factorization involves using the pairs and the unpaired factor.</p>

21 <p><strong>Step 2:</strong>Now we need to find n whose square is 12. We can say n as ‘3’ because 3 x 3 is lesser than or equal to 12. Now the<a>quotient</a>is 3 after subtracting 9 (3^2) from 12, the<a>remainder</a>is 3.</p>

22 <p><strong>Step 3:</strong>Now let us bring down 80, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number 3 + 3 to get 6, which will be our new divisor.</p>

23 <p><strong>Step 4:</strong>Find a number n such that 6n x n ≤ 380. Let us consider n as 5, now 65 x 5 = 325.</p>

22 <p><strong>Step 4:</strong>Find a number n such that 6n x n ≤ 380. Let us consider n as 5, now 65 x 5 = 325.</p>

24 <p><strong>Step 5:</strong>Subtract 325 from 380; the difference is 55, and the quotient is 35.</p>

23 <p><strong>Step 5:</strong>Subtract 325 from 380; the difference is 55, and the quotient is 35.</p>

25 <p><strong>Step 6:</strong>Since the dividend is<a>less than</a>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 5500.</p>

26 <p><strong>Step 7:</strong>Now we need to find the new divisor that is 707 because 707 x 7 = 4949.</p>

25 <p><strong>Step 7:</strong>Now we need to find the new divisor that is 707 because 707 x 7 = 4949.</p>

27 <p><strong>Step 8:</strong>Subtracting 4949 from 5500, we get the result 551.</p>

28 <p><strong>Step 9:</strong>Continue doing these steps until we get two numbers after the decimal point.</p>

37 <h3>Problem 1</h3>

38 <p>Can you help Max find the area of a square box if its side length is given as √320?</p>

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

40 <p>The area of the square is 320 square units.</p>

41 <h3>Explanation</h3>

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

43 <p>The side length is given as √320.</p>

44 <p>Area of the square = side^2 = √320 x √320 = 320.</p>

45 <p>Therefore, the area of the square box is 320 square units.</p>

46 <p>Well explained 👍</p>

47 <h3>Problem 2</h3>

48 <p>A square-shaped building measuring 1280 square feet is built; if each of the sides is √1280, what will be the square feet of half of the building?</p>

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

50 <p>640 square meters</p>

51 <h3>Explanation</h3>

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

53 <p>Dividing 1280 by 2 = we get 640.</p>

54 <p>So half of the building measures 640 square meters.</p>

55 <p>Well explained 👍</p>

60 <h3>Explanation</h3>

61 <p>The first step is to find the square root of 1280, which is approximately 35.7771.</p>

62 <p>The second step is to multiply 35.7771 by 5.</p>

63 <p>So 35.7771 x 5 ≈ 178.8855.</p>

64 <p>Well explained 👍</p>

66 <p>What will be the square root of (320 + 10)?</p>

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

68 <p>The square root is approximately 18.2483.</p>

69 <h3>Explanation</h3>

70 <p>To find the square root, we need to find the sum of (320 + 10).</p>

71 <p>320 + 10 = 330, and then √330 ≈ 18.2483.</p>

72 <p>Therefore, the square root of (320 + 10) is approximately ±18.2483.</p>

73 <p>Well explained 👍</p>

74 <h3>Problem 5</h3>

75 <p>Find the perimeter of the rectangle if its length ‘l’ is √320 units and the width ‘w’ is 38 units.</p>

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

77 <p>We find the perimeter of the rectangle as approximately 115.5482 units.</p>

78 <h3>Explanation</h3>

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

80 <p>Perimeter = 2 × (√320 + 38)</p>

81 <p>= 2 × (17.8885 + 38)</p>

82 <p>≈ 2 × 55.7741</p>

83 <p>≈ 111.5482 units.</p>
