Square Root of 2080
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 like vehicle design, finance, etc. Here, we will discuss the square root of 2080.
What is the Square Root of 2080?
The square root is the inverse of the square of the number. 2080 is not a perfect square. The square root of 2080 is expressed in both radical and exponential form. In the radical form, it is expressed as √2080, whereas (2080)^(1/2) in exponential form. √2080 ≈ 45.607, 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 2080
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 2080 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 2080 is broken down into its prime factors.
Step 1: Finding the prime factors of 2080.
Breaking it down, we get 2 x 2 x 2 x 2 x 5 x 13: 2^4 x 5 x 13.
Step 2: Now that we found the prime factors of 2080, the second step is to make pairs of those prime factors. Since 2080 is not a perfect square, the digits of the number can’t be grouped in pairs perfectly. Therefore, calculating √2080 using prime factorization is complex.
Square Root of 2080 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 2080, we need to group it as 80 and 20.
Step 2: Now we need to find n whose square is less than or equal to 20. We can say n is ‘4’ because 4 x 4 = 16, which is less than 20. Now the quotient is 4 after subtracting 16 from 20, the remainder is 4.
Step 3: Now let us bring down 80 which is the new dividend. Add the old divisor with the same number, 4 + 4, we get 8, which will be our new divisor.
Step 4: The new divisor will be 8n. We need to find the value of n where 8n x n is less than or equal to 480.
Step 5: The next step is finding 8n x n ≤ 480. Let us consider n as 5, now 85 x 5 = 425.
Step 6: Subtract 425 from 480, the difference is 55, and the quotient is 45.
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 5500.
Step 8: Now we need to find the new divisor that is 912 because 912 x 6 = 5472.
Step 9: Subtracting 5472 from 5500, we get the result 28.
Step 10: Now the quotient is 45.6.
Step 11: 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 √2080 is approximately 45.61.
Square Root of 2080 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 2080 using the approximation method.
Step 1: Now we have to find the closest perfect square of √2080. The smallest perfect square less than 2080 is 2025, and the largest perfect square greater than 2080 is 2116. √2080 falls somewhere between 45 and 46.
Step 2: Now we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula (2080 - 2025) ÷ (2116 - 2025) = 55 ÷ 91 ≈ 0.604.
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 45 + 0.604 = 45.604, so the square root of 2080 is approximately 45.604.
Common Mistakes and How to Avoid Them in the Square Root of 2080
Students do make mistakes while finding the square root, such as forgetting about the negative square root, 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 children make. To resolve this we need to teach children that simplifying the numbers inside the square root is important and then move on to the second step.
For Example: √(12 + 24) = √12 + √24 is a 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 ≈ 7.071067.
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, resulting in a wrong answer at the end of the sum. This may either happen in subtracting or elsewhere.
Square Root of 2080 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √2080?
The area of the square is approximately 2080 square units.
Explanation
The area of the square = side^2.
The side length is given as √2080.
Area of the square = side^2 = √2080 x √2080 = 2080.
Therefore, the area of the square box is approximately 2080 square units.
Problem 2
A square-shaped building measuring 2080 square feet is built; if each of the sides is √2080, what will be the square feet of half of the building?
1040 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 2080 by 2 = we get 1040.
So half of the building measures 1040 square feet.
Problem 3
Calculate √2080 x 5.
228.035
Explanation
The first step is to find the square root of 2080, which is approximately 45.607.
The second step is to multiply 45.607 with 5.
So 45.607 x 5 = 228.035.
Problem 4
What will be the square root of (2080 + 16)?
The square root is approximately 46.
Explanation
To find the square root, we need to find the sum of (2080 + 16). 2080 + 16 = 2096, and then √2096 ≈ 45.77.
Therefore, the square root of (2080 + 16) is approximately 45.77.
Problem 5
Find the perimeter of the rectangle if its length ‘l’ is √2080 units and the width ‘w’ is 38 units.
The perimeter of the rectangle is approximately 167.214 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√2080 + 38) = 2 × (45.607 + 38) ≈ 2 × 83.607 ≈ 167.214 units.
