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 such as vehicle design, finance, etc. Here, we will discuss the square root of 1029.
The square root is the inverse of the square of the number. 1029 is not a perfect square. The square root of 1029 is expressed in both radical and exponential form. In the radical form, it is expressed as √1029, whereas \(1029^{1/2}\) is in exponential form. √1029 ≈ 32.085, 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 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 1029 is broken down into its prime factors:
Step 1: Finding the prime factors of 1029 Breaking it down, we get 3 x 3 x 3 x 7 x 17: \(3^3 \times 7 \times 17\)
Step 2: Now we found out the prime factors of 1029. The second step is to make pairs of those prime factors. Since 1029 is not a perfect square, therefore the digits of the number can’t be grouped in pairs.
Therefore, calculating √1029 using prime factorization is not feasible for finding an exact whole number.
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 1029, we need to group it as 29 and 10.
Step 2: Now we need to find n whose square is closest to 10. We can say n as ‘3’ because \(3 \times 3 = 9\) is lesser than or equal to 10. Now the quotient is 3; after subtracting 9 from 10, the remainder is 1.
Step 3: Now let us bring down 29, which is the new dividend. Add the old divisor with the same number: 3 + 3 = 6, which will be our new divisor.
Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 6n as the new divisor; we need to find the value of n.
Step 5: The next step is finding \(6n \times n \leq 129\). Let us consider n as 2; now \(6 \times 2 \times 2 = 124\).
Step 6: Subtract 124 from 129; the difference is 5, 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 500.
Step 8: Now we need to find the new divisor that is 642 because \(642 \times 1 = 642\).
Step 9: Subtracting 642 from 5000, we continue the process further for more precision.
Step 10: 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 √1029 is approximately 32.085.
The approximation method is another method for finding the 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 1029 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √1029. The smallest perfect square less than 1029 is 1024 (which is \(32^2\)), and the largest perfect square greater than 1029 is 1089 (which is \(33^2\)). √1029 falls somewhere between 32 and 33.
Step 2: Now we need to apply the formula that is \((\text{Given number} - \text{smallest perfect square}) / (\text{Greater perfect square} - \text{smallest perfect square})\). Going by the formula \((1029 - 1024) / (1089 - 1024) = 5/65 = 0.077\). 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 \(32 + 0.077 \approx 32.085\).
So the square root of 1029 is approximately 32.085.
Students do make mistakes while finding the square root, like forgetting about the negative square root and 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 √1029?
The area of the square is 1029 square units.
The area of the square = side².
The side length is given as √1029.
Area of the square = side²
= √1029 × √1029
= 1029.
Therefore, the area of the square box is 1029 square units.
A square-shaped garden measuring 1029 square feet is planned; if each of the sides is √1029, what will be the square feet of half of the garden?
514.5 square feet
We can just divide the given area by 2 as the garden is square-shaped.
Dividing 1029 by 2 = 514.5.
So half of the garden measures 514.5 square feet.
Calculate √1029 × 5.
160.425
The first step is to find the square root of 1029, which is approximately 32.085.
The second step is to multiply 32.085 with 5.
So 32.085 × 5 = 160.425.
What will be the square root of (1000 + 29)?
The square root is approximately 32.085.
To find the square root, we need to find the sum of (1000 + 29) = 1029.
The square root of 1029 is approximately 32.085.
Therefore, the square root of (1000 + 29) is approximately ±32.085.
Find the perimeter of the rectangle if its length ‘l’ is √1029 units and the width ‘w’ is 38 units.
The perimeter of the rectangle is approximately 140.17 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√1029 + 38)
= 2 × (32.085 + 38)
= 2 × 70.085
= 140.17 units.
