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 various fields like vehicle design, finance, etc. Here, we will discuss the square root of 977.</p>

4 <h2>What is the Square Root of 977?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of a<a>number</a>. 977 is not a<a>perfect square</a>. The square root of 977 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √977, whereas (977)(1/2) is the exponential form. √977 ≈ 31.2569992, 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 977</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 long-<a>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 977 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 977 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 977 977 is a<a>prime number</a>itself. Hence, it cannot be broken down into smaller prime factors.</p>

14 <p>Since 977 is not a perfect square, calculating its<a>square root</a>using prime factorization is not feasible.</p>

19 <p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 977, we need to group it as 77 and 9.</p>

18 <p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 977, we need to group it as 77 and 9.</p>

20 <p><strong>Step 2:</strong>Now we need to find n whose square is ≤ 9. We can say n is ‘3’ because 3 x 3 = 9. Now the<a>quotient</a>is 3 and the<a>remainder</a>is 0 after subtracting 9 - 9.</p>

21 <p><strong>Step 3:</strong>Now let us bring down 77 which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number 3 + 3 = 6 which will be our new divisor.</p>

20 <p><strong>Step 3:</strong>Now let us bring down 77 which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number 3 + 3 = 6 which will be our new divisor.</p>

22 <p><strong>Step 4:</strong>The new divisor will be 6x. Now we need to find a digit x such that 6x x x ≤ 77. Trying x = 1, 61 x 1 = 61.</p>

21 <p><strong>Step 4:</strong>The new divisor will be 6x. Now we need to find a digit x such that 6x x x ≤ 77. Trying x = 1, 61 x 1 = 61.</p>

23 <p><strong>Step 5:</strong>Subtract 61 from 77, the remainder is 16.</p>

22 <p><strong>Step 5:</strong>Subtract 61 from 77, the remainder is 16.</p>

24 <p><strong>Step 6:</strong>Since the dividend is<a>less than</a>the divisor, we need to add a<a>decimal</a>point. Adding the decimal point allows us to add two zeroes to the dividend. The new dividend is 1600.</p>

23 <p><strong>Step 6:</strong>Since the dividend is<a>less than</a>the divisor, we need to add a<a>decimal</a>point. Adding the decimal point allows us to add two zeroes to the dividend. The new dividend is 1600.</p>

25 <p><strong>Step 7:</strong>The new divisor is 62 because 622 x 2 = 1244.</p>

24 <p><strong>Step 7:</strong>The new divisor is 62 because 622 x 2 = 1244.</p>

26 <p><strong>Step 8:</strong>Subtracting 1244 from 1600, we get the result 356. Step 9: Now the quotient is 31.2</p>

25 <p><strong>Step 8:</strong>Subtracting 1244 from 1600, we get the result 356. Step 9: Now the quotient is 31.2</p>

27 <p><strong>Step 10:</strong>Continue doing these steps until we get the desired precision. Suppose if there are no decimal values, continue till the remainder is zero.</p>

31 <p><strong>Step 1:</strong>Now we have to find the closest perfect square of √977. The smallest perfect square less than 977 is 961 (31 x 31), and the largest perfect square<a>greater than</a>977 is 1024 (32 x 32). Therefore, √977 falls somewhere between 31 and 32.</p>

30 <p><strong>Step 1:</strong>Now we have to find the closest perfect square of √977. The smallest perfect square less than 977 is 961 (31 x 31), and the largest perfect square<a>greater than</a>977 is 1024 (32 x 32). Therefore, √977 falls somewhere between 31 and 32.</p>

31 <p><strong>Step 2:</strong>Now we need to apply the<a>formula</a>: (Given number - smallest perfect square) ÷ (Greater perfect square - smallest perfect square)</p>

33 <p>Using the formula (977 - 961) ÷ (1024 - 961) = 16 ÷ 63 ≈ 0.254 Using the formula we identified the decimal point of our square root.</p>

32 <p>Using the formula (977 - 961) ÷ (1024 - 961) = 16 ÷ 63 ≈ 0.254 Using the formula we identified the decimal point of our square root.</p>

34 <p>The next step is adding the value we got initially to the decimal number which is 31 + 0.254 ≈ 31.254, so the square root of 977 is approximately 31.254.</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 √977?</p>

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

40 <p>The area of the square is approximately 977 square units.</p>

41 <h3>Explanation</h3>

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

43 <p>The side length is given as √977.</p>

44 <p>Area of the square = side2 = √977 x √977 = 977.</p>

45 <p>Therefore, the area of the square box is approximately 977 square units.</p>

46 <p>Well explained 👍</p>

47 <h3>Problem 2</h3>

48 <p>A square-shaped building measuring 977 square feet is built; if each of the sides is √977, what will be the square feet of half of the building?</p>

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

50 <p>488.5 square feet</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 977 by 2 = 488.5.</p>

54 <p>So, half of the building measures 488.5 square feet.</p>

55 <p>Well explained 👍</p>
