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 various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 1071.
The square root is the inverse of the square of a number. 1071 is not a perfect square. The square root of 1071 is expressed in both radical and exponential form. In the radical form, it is expressed as √1071, whereas (1071)^(1/2) in the exponential form. √1071 ≈ 32.718, 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, the prime factorization method is not used for non-perfect square numbers where the long division method and approximation method are used. Let us now learn the following methods:
The product of prime factors is the prime factorization of a number. Now let us look at how 1071 is broken down into its prime factors:
Step 1: Finding the prime factors of 1071 Breaking it down, we get 3 x 3 x 7 x 17: 3^2 x 7 x 17
Step 2: Now we found out the prime factors of 1071. The second step is to make pairs of those prime factors. Since 1071 is not a perfect square, the digits of the number can’t be grouped in pairs.
Therefore, calculating √1071 using prime factorization alone is not precise.
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 1071, we need to group it as 71 and 10.
Step 2: Now we need to find n whose square is less than or equal to 10. We can say n is ‘3’ because 3 x 3 = 9, which is less than 10. Now the quotient is 3 after subtracting 10 - 9, the remainder is 1.
Step 3: Bring down 71, making the new dividend 171. Add the old divisor with the same number 3 + 3, we get 6, which will be our new divisor.
Step 4: The new divisor will be the sum of the previous divisor and a number. Now we get 6n as the new divisor, we need to find the value of n.
Step 5: The next step is finding 6n x n ≤ 171. Let us consider n as 2, now 62 x 2 = 124.
Step 6: Subtract 171 from 124. The difference is 47, and the quotient is 32.
Step 7: Since the dividend is less than 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 4700.
Step 8: Now we need to find the new divisor. Trying 649 x 7 = 4543.
Step 9: Subtracting 4543 from 4700, we get the result 157.
Step 10: Now the quotient is 32.7.
Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there are no decimal values, continue till the remainder is zero.
So the square root of √1071 is approximately 32.718.
The approximation method is another method for finding square roots; it is an easy method to find the square root of a given number. Now let us learn how to find the square root of 1071 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √1071. The smallest perfect square less than 1071 is 1024, and the largest perfect square greater than 1071 is 1089. √1071 falls somewhere between 32 and 33.
Step 2: Now we need to apply the formula that is (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Using the formula (1071 - 1024) / (1089 - 1024) = 0.723. Using the formula, we identified the decimal point of our square root. The next step is adding the value we got initially to the decimal number, which is 32 + 0.723 = 32.723.
So the square root of 1071 is approximately 32.723.
Students often make mistakes while finding square roots, such as forgetting about the negative square root, skipping long division steps, etc. Now let us look at a few of those mistakes students tend to make in detail.
Can you help Max find the area of a square box if its side length is given as √1071?
The area of the square is approximately 1071 square units.
The area of the square = side².
The side length is given as √1071.
Area of the square = side²
= √1071 x √1071
= 1071.
Therefore, the area of the square box is approximately 1071 square units.
A square-shaped building measuring 1071 square feet is built; if each of the sides is √1071, what will be the square feet of half of the building?
Approximately 535.5 square feet.
We can just divide the given area by 2 as the building is square-shaped.
Dividing 1071 by 2 = 535.5.
So half of the building measures approximately 535.5 square feet.
Calculate √1071 x 5.
Approximately 163.59.
The first step is to find the square root of 1071, which is approximately 32.718.
The second step is to multiply 32.718 by 5.
So 32.718 x 5 ≈ 163.59.
What will be the square root of (1024 + 47)?
The square root is 33.
To find the square root, we need to find the sum of (1024 + 47).
1024 + 47 = 1071, and then √1071 ≈ 32.718.
Therefore, the square root of (1024 + 47) is approximately 32.718.
Find the perimeter of the rectangle if its length ‘l’ is √1071 units and the width ‘w’ is 40 units.
The perimeter of the rectangle is approximately 145.436 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√1071 + 40)
= 2 × (32.718 + 40)
≈ 2 × 72.718
= 145.436 units.
