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 2017.
The square root is the inverse of the square of a number. 2017 is not a perfect square. The square root of 2017 is expressed in both radical and exponential form. In the radical form, it is expressed as √2017, whereas in exponential form it is (2017)^(1/2). √2017 ≈ 44.911, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.
The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, the prime factorization method is not applicable, so we use the long-division method and approximation method. Let us now learn the following methods:
The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step:
Step 1: To begin with, we need to group the numbers from right to left. In the case of 2017, group it as 20 and 17.
Step 2: Now, find n whose square is less than or equal to 20. We can say n as '4' because 4 × 4 = 16 is less than 20. The quotient is 4; after subtracting 16 from 20, the remainder is 4.
Step 3: Bring down 17 to make it 417. Add the old divisor (4) with the same number (4) to get 8, which will be our new divisor.
Step 4: The new divisor becomes 8n. We need to find the value of n such that 8n × n ≤ 417. Let us consider n as 5; now 85 × 5 = 425, which is more than 417. Try n as 4; 84 × 4 = 336.
Step 5: Subtract 336 from 417; the difference is 81. The quotient is 44.
Step 6: Since 81 is the remainder, we need to add a decimal point and continue the process. Add two zeroes to make it 8100.
Step 7: Now find the new divisor, which is 889, because 889 × 9 = 8001.
Step 8: Subtracting 8001 from 8100 gives us 99.
Step 9: Continue doing these steps until we get two numbers after the decimal point.
Thus, the square root of √2017 is approximately 44.91.
The approximation method is another method for finding square roots, and it is an easy method for estimating the square root of a given number. Let us learn how to find the square root of 2017 using the approximation method.
Step 1: Find the closest perfect squares around √2017. The smallest perfect square less than 2017 is 1936 (44^2), and the largest perfect square greater than 2017 is 2025 (45^2). √2017 lies between 44 and 45.
Step 2: Apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). (2017 - 1936) / (2025 - 1936) = 81 / 89 ≈ 0.91 Adding this decimal to the lower bound gives 44 + 0.91 = 44.91, so the square root of 2017 is approximately 44.91.
Students make mistakes while finding the square root, such as forgetting about the negative square root, skipping long division methods, etc. Now let us look at a few of those mistakes that students tend to make in detail.
Can you help Max find the area of a square box if its side length is given as √1033?
The area of the square is approximately 1033 square units.
The area of the square = side^2.
The side length is given as √1033.
Area = side^2 = √1033 × √1033 = 1033.
Therefore, the area of the square box is approximately 1033 square units.
A square-shaped building measuring 2017 square feet is built; if each of the sides is √2017, what will be the square feet of half of the building?
1008.5 square feet
We can divide the given area by 2 as the building is square-shaped.
Dividing 2017 by 2 gives us 1008.5.
So, half of the building measures 1008.5 square feet.
Calculate √2017 × 5.
≈ 224.555
The first step is to find the square root of 2017, which is approximately 44.911.
Then multiply 44.911 by 5.
So, 44.911 × 5 ≈ 224.555.
What will be the square root of (981 + 36)?
The square root is 33.
To find the square root, we need to find the sum of (981 + 36). 981 + 36 = 1017. √1017 ≈ 31.87, approximately 32.
Therefore, the square root of (981 + 36) is approximately 32.
Find the perimeter of the rectangle if its length ‘l’ is √1033 units and the width ‘w’ is 25 units.
We find the perimeter of the rectangle as approximately 139.82 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√1033 + 25) ≈ 2 × (32.14 + 25) ≈ 2 × 57.14 ≈ 114.28 units.
