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 20000.</p>

4 <h2>What is the Square Root of 20000?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. 20000 is not a<a>perfect square</a>. The square root of 20000 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √20000, whereas (20000)(1/2) in the exponential form. √20000 ≈ 141.421, 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<a>long division</a>method and approximation method are used. Let us now learn the following methods:</p>

8 <ol><li>Prime factorization method</li>

9 <li>Long division method</li>

10 <li>Approximation method</li>

11 </ol><h2>Square Root of 20000 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 20000 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 20000 Breaking it down, we get 2 x 2 x 2 x 2 x 5 x 5 x 5 x 5 x 5: 24 x 55</p>

14 <p><strong>Step 2:</strong>Now we found out the prime factors of 20000. The second step is to make pairs of those prime factors. Since 20000 is not a perfect square, therefore the digits of the number can’t be grouped in a perfect pair.</p>

15 <p>Therefore, calculating √20000 using prime factorization is impossible.</p>

21 <p><strong>Step 2</strong>: Now we need to find n whose square is 20. We can say n as ‘4’ because 4 × 4 is lesser than or equal to 20. Now the<a>quotient</a>is 4, and after subtracting 16 from 20, the<a>remainder</a>is 4.</p>

22 <p><strong>Step 3:</strong>Now let us bring down 00, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number 4 + 4 to get 8, which will be our new divisor.</p>

21 <p><strong>Step 3:</strong>Now let us bring down 00, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number 4 + 4 to get 8, which will be our new divisor.</p>

23 <p><strong>Step 4:</strong>The new divisor will be 8n. Now we need to find the value of n.</p>

22 <p><strong>Step 4:</strong>The new divisor will be 8n. Now we need to find the value of n.</p>

24 <p><strong>Step 5:</strong>The next step is finding 8n × n ≤ 400. Let us consider n as 5, now 8 × 5 × 5 = 400.</p>

23 <p><strong>Step 5:</strong>The next step is finding 8n × n ≤ 400. Let us consider n as 5, now 8 × 5 × 5 = 400.</p>

25 <p><strong>Step 6:</strong>Subtract 400 from 400, the difference is 0, and the quotient is 45.</p>

24 <p><strong>Step 6:</strong>Subtract 400 from 400, the difference is 0, and the quotient is 45.</p>

26 <p><strong>Step 7:</strong>Since the dividend is zero, we have our quotient as 141.42. So the square root of √20000 ≈ 141.42</p>

35 <h3>Problem 1</h3>

36 <p>Can you help Max find the area of a square box if its side length is given as √20000?</p>

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

38 <p>The area of the square is 20000 square units.</p>

39 <h3>Explanation</h3>

40 <p>The area of the square = side2.</p>

41 <p>The side length is given as √20000.</p>

42 <p>Area of the square = side2 = √20000 × √20000 = 20000.</p>

43 <p>Therefore, the area of the square box is 20000 square units.</p>

45 <h3>Problem 2</h3>

46 <p>A square-shaped building measuring 20000 square feet is built; if each of the sides is √20000, what will be the square feet of half of the building?</p>

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

48 <p>10000 square feet</p>

49 <h3>Explanation</h3>

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

51 <p>Dividing 20000 by 2 gives us 10000.</p>

52 <p>So half of the building measures 10000 square feet.</p>

67 <h3>Explanation</h3>

68 <p>To find the square root, we need to find the sum of (19800 + 200).</p>

69 <p>19800 + 200 = 20000, and then √20000 ≈ 141.421.</p>
