Square Root of 608
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 608.
What is the Square Root of 608?
The square root is the inverse of the square of the number. 608 is not a perfect square. The square root of 608 is expressed in both radical and exponential form. In the radical form, it is expressed as √608, whereas (608)^(1/2) in the exponential form. √608 ≈ 24.657, 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 608
The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers, where the 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 608 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 608 is broken down into its prime factors.
Step 1: Finding the prime factors of 608 Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 19 = 2^5 x 19
Step 2: Now we found out the prime factors of 608. The second step is to make pairs of those prime factors. Since 608 is not a perfect square, the digits of the number can't be grouped in pairs completely. Therefore, calculating 608 using prime factorization leaves us with a residual factor.
Square Root of 608 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 608, we need to group it as 08 and 6.
Step 2: Now we need to find n whose square is ≤ 6. We can say n is '2' because 2 x 2 = 4, which is lesser than or equal to 6. Now the quotient is 2, and after subtracting 4 from 6, the remainder is 2.
Step 3: Now let us bring down 08, 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: The new divisor will be 4n. We need to find the value of n.
Step 5: The next step is finding 4n x n ≤ 208. Let us consider n as 5, now 45 x 5 = 225, which is more than 208, so we consider n as 4.
Step 6: 44 x 4 = 176. Subtracting 176 from 208, the difference is 32, and the quotient is 24.
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 3200.
Step 8: Now we need to find the new divisor, which is 4n. Let's assume n as 6, 496 x 6 = 2976.
Step 9: Subtracting 2976 from 3200, we get the result 224.
Step 10: Now the quotient is 24.6
Step 11: Continue doing these steps until we get two numbers after the decimal point. If there is no decimal value, continue until the remainder is zero. So the square root of √608 is approximately 24.66.
Square Root of 608 by Approximation Method
The approximation method is another method 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 608 using the approximation method.
Step 1: Now we have to find the closest perfect square of √608. The smallest perfect square less than 608 is 576 (24^2), and the largest perfect square greater than 608 is 625 (25^2). √608 falls somewhere between 24 and 25.
Step 2: Now we need to apply the formula that is (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) Going by the formula (608 - 576) ÷ (625 - 576) = 32 / 49 ≈ 0.653 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 24 + 0.653 ≈ 24.653. So the square root of 608 is approximately 24.653.
Common Mistakes and How to Avoid Them in the Square Root of 608
Students do make mistakes while finding the square root, like forgetting about the negative square root or skipping long division methods, etc. 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 the square root symbol in proper places
Not using the square root properly is another mistake that students make. To resolve this, we need to teach students that simplifying the numbers inside the square root is important before moving on to the second step.
For example: √(12+24) = √12 + √24 is an incorrect 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 students 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 incorrect, 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 608 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √408?
The area of the square is approximately 408 square units.
Explanation
The area of the square = side^2.
The side length is given as √408.
Area of the square = side^2 = √408 x √408 = 408
Therefore, the area of the square box is approximately 408 square units.
Problem 2
A square-shaped building measuring 608 square feet is built; if each of the sides is √608, what will be the square feet of half of the building?
304 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 608 by 2, we get 304.
So half of the building measures 304 square feet.
Problem 3
Calculate √608 x 5.
Approximately 123.285
Explanation
The first step is to find the square root of 608, which is approximately 24.657.
The second step is to multiply 24.657 by 5.
So 24.657 x 5 ≈ 123.285.
Problem 4
What will be the square root of (400 + 8)?
The square root is approximately 20.1.
Explanation
To find the square root, we need to find the sum of (400 + 8).
400 + 8 = 408, and then √408 ≈ 20.1.
Therefore, the square root of (400 + 8) is approximately ±20.1.
Problem 5
Find the perimeter of the rectangle if its length 'l' is √608 units and the width 'w' is 38 units.
We find the perimeter of the rectangle as approximately 125.314 units.
Explanation
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√608 + 38) ≈ 2 × (24.657 + 38) ≈ 2 × 62.657 ≈ 125.314 units.
