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 engineering, physics, and finance. Here, we will discuss the square root of 578.
The square root is the inverse of the square of a number. 578 is not a perfect square. The square root of 578 is expressed in both radical and exponential forms. In the radical form, it is expressed as √578, whereas (578)^(1/2) is the exponential form. √578 ≈ 24.04163, 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, for non-perfect square numbers like 578, 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 578 is broken down into its prime factors:
Step 1: Find the prime factors of 578. Breaking it down, we get 2 x 17 x 17: 2^1 x 17^2
Step 2: Now we found out the prime factors of 578. The second step is to make pairs of those prime factors. Since 578 is not a perfect square, the digits of the number can’t be grouped into pairs. Therefore, calculating the square root of 578 using prime factorization alone does not provide an exact result.
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 578, we need to group it as 78 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 x 2 = 4 is less than 5. Now the quotient is 2. After subtracting 4 from 5, the remainder is 1.
Step 3: Bring down 78, which is the new dividend. Add the old divisor with the same number 2 + 2, we get 4, which will be our new divisor.
Step 4: Find 4n such that 4n × n ≤ 178. Let us consider n as 4, now 44 x 4 = 176.
Step 5: Subtract 176 from 178, the difference is 2, and the quotient is 24.
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 200.
Step 7: Find the new divisor which is 48 because 480 x 0 = 0
Step 8: Subtract the product from 200 to continue the long division.
Step 9: Continue doing these steps until we get two numbers after the decimal point. If there is no decimal value, continue till the remainder is zero.
So the square root of √578 ≈ 24.04163.
The approximation method is another approach 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 578 using the approximation method.
Step 1: Now we have to find the closest perfect squares around √578. The smallest perfect square less than 578 is 576 and the largest perfect square greater than 578 is 625. √578 falls somewhere between √576 (24) and √625 (25).
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 (578 - 576) / (625 - 576) ≈ 0.04163. Using this formula, we identified the decimal point of our square root. The next step is adding the whole number we predicted initially to the decimal number: 24 + 0.04163 ≈ 24.04163, so the square root of 578 is approximately 24.04163.
Students do make mistakes while finding the square root, like forgetting about the negative square root, skipping steps in the long division method, etc. Now let us look at a few of these mistakes in detail.
Can you help Alex find the area of a square box if its side length is given as √578?
The area of the square is 578 square units.
The area of the square = side^2.
The side length is given as √578.
Area of the square = (√578)^2 = 578 square units.
Therefore, the area of the square box is 578 square units.
A square-shaped garden measuring 578 square feet is built; if each of the sides is √578, what will be the square feet of half of the garden?
289 square feet
We can just divide the given area by 2 as the garden is square-shaped.
Dividing 578 by 2 gives us 289. So half of the garden measures 289 square feet.
Calculate √578 x 3.
72.12489
The first step is to find the square root of 578, which is approximately 24.04163.
The second step is to multiply 24.04163 by 3.
So 24.04163 x 3 ≈ 72.12489.
What will be the square root of (144 + 434)?
The square root is approximately 24.04163.
To find the square root, we need to find the sum of (144 + 434). 144 + 434 = 578, and then √578 ≈ 24.04163.
Therefore, the square root of (144 + 434) is approximately 24.04163.
Find the perimeter of a rectangle if its length ‘l’ is √578 units and the width ‘w’ is 20 units.
The perimeter of the rectangle is approximately 88.08326 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√578 + 20) = 2 × (24.04163 + 20) ≈ 2 × 44.04163 = 88.08326 units.
