Square Root of 574
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 the field of vehicle design, finance, etc. Here, we will discuss the square root of 574.
What is the Square Root of 574?
The square root is the inverse of the square of the number. 574 is not a perfect square. The square root of 574 is expressed in both radical and exponential form. In the radical form, it is expressed as √574, whereas (574)^(1/2) in the exponential form. √574 ≈ 23.9583, 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.
Finding the Square Root of 574
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:
- Prime factorization method
- Long division method
- Approximation method
Square Root of 574 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 574 is broken down into its prime factors:
Step 1: Finding the prime factors of 574. Breaking it down, we get 2 x 287: 2^1 x 287^1.
Step 2: Now we found out the prime factors of 574. The second step is to make pairs of those prime factors. Since 574 is not a perfect square, the digits of the number can’t be grouped in pairs.
Therefore, calculating 574 using prime factorization is impossible.
Square Root of 574 by Long Division Method
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 574, we need to group it as 74 and 5.
Step 2: Now we need to find n whose square is less than or equal to 5. We can say n as '2' because 2^2 = 4 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 74, which is the new dividend. Add the old divisor with the same number 2 + 2 to get 4, which will be our new divisor.
Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 4n as the new divisor, and we need to find the value of n.
Step 5: The next step is finding 4n × n ≤ 174. Let us consider n as 4, now 44 x 4 = 176.
Step 6: Since 176 is greater than 174, we try n = 3, then 43 x 3 = 129.
Step 7: Subtract 129 from 174, the difference is 45, and the quotient is 23.
Step 8: Since the dividend is greater than the divisor, add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 4500.
Step 9: Now we need to find the new divisor that is 239 because 2399 x 9 = 4311. Step 10: Subtracting 4311 from 4500, we get the result 189.
Step 11: The quotient is now 23.9. Continue doing these steps until we get two numbers after the decimal point. Suppose if there is no decimal value, continue till the remainder is zero.
So the square root of √574 is approximately 23.96.
Square Root of 574 by Approximation Method
The approximation method is another method for finding square roots, and 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 574 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √574. The smallest perfect square less than 574 is 529, and the largest perfect square greater than 574 is 576. √574 falls somewhere between 23 and 24.
Step 2: Now we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula: (574 - 529) / (576 - 529) = 45 / 47 ≈ 0.957. 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 + 0.957 = 23.957, so the square root of 574 is approximately 23.96.
Common Mistakes and How to Avoid Them in the Square Root of 574
Students do make mistakes while finding the square root, like forgetting about the negative square root or skipping long division methods. Now let us look at a few of those mistakes that students tend to make in detail.
Mistake 1
Forgetting about the negative square root
It is important to make students aware that a number does have both positive and negative square roots. However, we will be taking only the positive square root, as it is the required one.
For example, √50 = 7.07, there is also -7.07 which should not be forgotten.
Mistake 2
Not adding square root symbol in proper places
Not using the square root properly is another mistake that children make. To resolve this, we need to teach children that simplifying the numbers inside the square root is important before moving on to the second step.
For example, √(12+24) = √12 + √24 is the wrong method of using roots. The right way of using roots is √(12+24) = √36.
Mistake 3
Not finding the correct value of a non-perfect square
The first step that needs to be taught to children is to simplify the numbers inside the square root. This is important so that students do not make mistakes while identifying the approximate value.
For example, √50 ≈ 7 is wrong; the correct answer is √50 ≈ 7.071.
Mistake 4
Confusing the square root symbol with the cube root
Students need to be taught the difference between cube root and square root constantly, as this will help them avoid mistakes.
For example, √50 and ∛50 are different.
Mistake 5
Making mistakes in long division
Finding a square root using the long division method involves many steps. Due to this, many students might skip a step accidentally, which results in a wrong answer at the end of the sum. This may either happen in subtracting or elsewhere.
Square Root of 574 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √574?
The area of the square is approximately 574 square units.
Explanation
The area of the square = side^2.
The side length is given as √574.
Area of the square = side^2 = √574 × √574 = 574.
Therefore, the area of the square box is approximately 574 square units.
Problem 2
A square-shaped building measuring 574 square feet is built; if each of the sides is √574, what will be the square feet of half of the building?
287 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 574 by 2, we get 287.
So half of the building measures 287 square feet.
Problem 3
Calculate √574 × 5.
119.79
Explanation
The first step is to find the square root of 574, which is approximately 23.96.
The second step is to multiply 23.96 by 5. So 23.96 × 5 ≈ 119.79.
Problem 4
What will be the square root of (529 + 45)?
The square root is approximately 23.96
Explanation
To find the square root, we need to find the sum of (529 + 45).
529 + 45 = 574, and then √574 ≈ 23.96.
Therefore, the square root of (529 + 45) is approximately ±23.96.
Problem 5
Find the perimeter of the rectangle if its length ‘l’ is √574 units and the width ‘w’ is 38 units.
The perimeter of the rectangle is approximately 123.92 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√574 + 38) = 2 × (23.96 + 38) ≈ 2 × 61.96 ≈ 123.92 units.
