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 like physics, engineering, and finance. Here, we will discuss the square root of 202.</p>

4 <h2>What is the Square Root of 202?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>squaring a<a>number</a>. 202 is not a<a>perfect square</a>. The square root of 202 is expressed in both radical and<a>exponential form</a>. In radical form, it is expressed as √202, whereas in exponential form it is (202)^(1/2). √202 ≈ 14.21267, which is an<a>irrational number</a>because it cannot be expressed as a<a>fraction</a>p/q, where p and q are integers and q ≠ 0.</p>

6 <h2>Finding the Square Root of 202</h2>

7 <p>The<a>prime factorization</a>method is used for perfect square numbers. However, for non-perfect square numbers like 202, the<a>long 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 202 by Prime Factorization Method</h2>

12 <p>The prime factorization of a number is the<a>product</a>of its prime<a>factors</a>. Now let us break down 202 into its prime factors:</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 202 Breaking it down, we get 2 x 101: 2^1 x 101^1</p>

14 <p><strong>Step 2:</strong>Since 202 is not a perfect square, the digits cannot be paired up evenly. Therefore, calculating 202 using prime factorization directly is not feasible for finding an exact<a>square root</a>.</p>

20 <p><strong>Step 2:</strong>Find n such that n^2 is<a>less than</a>or equal to 2. We choose n = 1 because 1^2 is 1, which is less than 2. The<a>quotient</a>is 1; after subtracting 1 from 2, the<a>remainder</a>is 1.</p>

21 <p><strong>Step 3:</strong>Bring down 02, making the new<a>dividend</a>102. Add the old<a>divisor</a>(1) to itself (1 + 1 = 2) to get the new divisor.</p>

20 <p><strong>Step 3:</strong>Bring down 02, making the new<a>dividend</a>102. Add the old<a>divisor</a>(1) to itself (1 + 1 = 2) to get the new divisor.</p>

22 <p><strong>Step 4:</strong>The new divisor is 2n. Now find n such that 2n x n is less than or equal to 102. Consider n = 4; then 2 x 4 x 4 = 32.</p>

21 <p><strong>Step 4:</strong>The new divisor is 2n. Now find n such that 2n x n is less than or equal to 102. Consider n = 4; then 2 x 4 x 4 = 32.</p>

23 <p><strong>Step 5:</strong>Subtract 32 from 102; the remainder is 70. The quotient is 14.</p>

22 <p><strong>Step 5:</strong>Subtract 32 from 102; the remainder is 70. The quotient is 14.</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 √202?</p>

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

39 <p>The area of the square is approximately 204.85 square units.</p>

40 <h3>Explanation</h3>

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

42 <p>The side length is given as √202.</p>

43 <p>Area of the square = (√202) x (√202) ≈ 14.21 x 14.21 ≈ 204.85</p>

44 <p>Therefore, the area of the square box is approximately 204.85 square units.</p>

45 <p>Well explained 👍</p>

46 <h3>Problem 2</h3>

47 <p>A square-shaped building measuring 202 square feet is built; if each of the sides is √202, what will be the square feet of half of the building?</p>

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

49 <p>101 square feet</p>

50 <h3>Explanation</h3>

51 <p>We can divide the given area by 2 as the building is square-shaped. Dividing 202 by 2 gives us 101.</p>

52 <p>So half of the building measures 101 square feet.</p>

53 <p>Well explained 👍</p>

54 <h3>Problem 3</h3>

55 <p>Calculate √202 x 5.</p>

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

57 <p>Approximately 71.06</p>

58 <h3>Explanation</h3>

59 <p>First, find the square root of 202, which is approximately 14.21, then multiply 14.21 by 5. So 14.21 x 5 ≈ 71.06</p>

62 <p>What will be the square root of (202 + 6)?</p>

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

64 <p>The square root is approximately 14.49</p>

65 <h3>Explanation</h3>

66 <p>To find the square root, first find the sum of (202 + 6). 202 + 6 = 208, then find √208 ≈ 14.49.</p>

67 <p>Therefore, the square root of (202 + 6) is approximately ±14.49.</p>

68 <p>Well explained 👍</p>
