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 engineering, finance, etc. Here, we will discuss the square root of 571.
The square root is the inverse of the square of the number. 571 is not a perfect square. The square root of 571 is expressed in both radical and exponential forms. In radical form, it is expressed as √571, whereas in exponential form, it is (571)^(1/2). √571 ≈ 23.882, which is an irrational number because it cannot be expressed as a fraction p/q, where p and q are integers and q ≠ 0.
The prime factorization method is typically used for perfect square numbers. However, for non-perfect square numbers like 571, the long division method and approximation method are used. Let us now learn these methods:
The product of prime factors is the prime factorization of a number. Now let us look at how 571 is broken down into its prime factors. Since 571 is a prime number, it cannot be factored further into smaller prime numbers. Therefore, calculating √571 using prime factorization is not applicable.
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 571, we need to group it as 71 and 5.
Step 2: Now we need to find n whose square is less than or equal to 5. We can say n is ‘2’ because 2^2 = 4, which is less than 5. Now the quotient is 2, and after subtracting 4 from 5, the remainder is 1.
Step 3: Now let us bring down 71, making the new dividend 171. Add the old divisor with the same number 2 + 2 to get 4, which will be our new divisor.
Step 4: The new divisor becomes 4n. We need to find the value of n such that 4n × n ≤ 171. Let us consider n as 4, then 44 × 4 = 176, which is greater than 171. Therefore, n is 3, and 43 × 3 = 129.
Step 5: Subtract 129 from 171, the difference is 42, and the quotient is 23.
Step 6: 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 4200.
Step 7: The new divisor becomes 466, and we find that 466 × 8 = 3728.
Step 8: Subtracting 3728 from 4200, we get a remainder of 472.
Step 9: The quotient is now 23.8. Continue these steps until we get two decimal places.
So the square root of √571 ≈ 23.88.
The approximation method is another method for finding the square roots. It's an easy way to find the square root of a given number. Now let us learn how to find the square root of 571 using the approximation method.
Step 1: Now we have to find the closest perfect squares to √571. The smallest perfect square less than 571 is 529, and the largest perfect square greater than 571 is 576. Thus, √571 falls between 23 and 24.
Step 2: Now we need to apply the formula for approximation: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Using the formula (571 - 529) / (576 - 529) = 42/47 ≈ 0.89. Adding this to the smaller square root, we get 23 + 0.89 = 23.89.
So the approximate square root of 571 is 23.89.
Students often make mistakes while finding square roots, such as forgetting about the negative square root or skipping steps in the long division method. Let's look at a few of the common mistakes in detail.
Can you help Max find the area of a square box if its side length is given as √451?
The area of the square is 451 square units.
The area of the square = side^2.
The side length is given as √451.
Area of the square = (√451)² = 451.
Therefore, the area of the square box is 451 square units.
A square-shaped plot of land measuring 571 square feet is built; if each side is √571, what will be the square feet of half of the plot?
285.5 square feet
To find half of the area of the square plot, we divide the given area by 2.
Dividing 571 by 2 gives us 285.5.
So half of the plot measures 285.5 square feet.
Calculate √571 × 5.
119.41
The first step is to find the square root of 571, which is approximately 23.88.
The second step is to multiply 23.88 by 5.
So 23.88 × 5 = 119.41.
What will be the square root of (551 + 20)?
The square root is 24.
To find the square root, we need to find the sum of (551 + 20). 551 + 20 = 571, and then √571 ≈ 23.88, which rounds to 24. Therefore, the square root of (551 + 20) is approximately 24.
Find the perimeter of the rectangle if its length ‘l’ is √571 units and the width ‘w’ is 38 units.
The perimeter of the rectangle is approximately 123.76 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√571 + 38) = 2 × (23.88 + 38) = 2 × 61.88 = 123.76 units.
