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 572.
The square root is the inverse of the square of the number. 572 is not a perfect square. The square root of 572 is expressed in both radical and exponential form. In the radical form, it is expressed as √572, whereas in the exponential form it is expressed as (572)^(1/2). √572 = 23.91652, 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 572 is broken down into its prime factors.
Step 1: Finding the prime factors of 572 Breaking it down, we get 2 × 2 × 11 × 13: 2^2 × 11 × 13
Step 2: Now that we have found the prime factors of 572, the second step is to make pairs of those prime factors. Since 572 is not a perfect square, the digits of the number can’t be grouped in pairs.
Therefore, calculating √572 using prime factorization is not straightforward.
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 572, we need to group it as 72 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 is 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 72, which is the new dividend. Add the old divisor with itself, 2 + 2, to get 4, which will be our new divisor.
Step 4: We have 4n as the new divisor, and we need to find the value of n such that 4n × n is less than or equal to 172. Let's consider n as 4. Now 44 × 4 = 176, which is greater than 172, so we choose n as 3.
Step 5: Subtract 144 (43 × 3) from 172, and the difference is 28. 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 2800.
Step 7: Now we need to find the new divisor, which is 46 because 463 × 3 = 1389.
Step 8: Subtract 1389 from 2800 to get the result of 1411.
Step 9: Continue doing these steps until we get two numbers after the decimal point or until the remainder is zero.
So the square root of √572 is approximately 23.92.
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 572 using the approximation method.
Step 1: Now we have to find the closest perfect square to √572. The smallest perfect square less than 572 is 529, and the largest perfect square greater than 572 is 576. √572 falls somewhere between 23 and 24.
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, (572 - 529) ÷ (576 - 529) = 43 ÷ 47 ≈ 0.9149 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 23 + 0.9149 = 23.9149.
So the square root of 572 is approximately 23.9149.
Students do make mistakes while finding the square root, such as forgetting about the negative square root and skipping steps in long division methods. 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 √572?
The area of the square is 572 square units.
The area of the square = side².
The side length is given as √572.
Area of the square = side² = √572 × √572 = 572.
Therefore, the area of the square box is 572 square units.
A square-shaped building measuring 572 square feet is built; if each of the sides is √572, what will be the square feet of half of the building?
286 square feet
We can just divide the given area by 2 as the building is square-shaped.
Dividing 572 by 2, we get 286.
So half of the building measures 286 square feet.
Calculate √572 × 5.
119.5826
The first step is to find the square root of 572, which is 23.91652.
The second step is to multiply 23.91652 with 5.
So 23.91652 × 5 ≈ 119.5826.
What will be the square root of (572 + 4)?
The square root is 24.
To find the square root, we need to find the sum of (572 + 4). 572 + 4 = 576, and then √576 = 24.
Therefore, the square root of (572 + 4) is ±24.
Find the perimeter of the rectangle if its length ‘l’ is √572 units and the width ‘w’ is 38 units.
We find the perimeter of the rectangle as 123.833 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√572 + 38) = 2 × (23.91652 + 38) = 2 × 61.91652 ≈ 123.833 units.
