Square Root of 2285
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 fields of vehicle design, finance, etc. Here, we will discuss the square root of 2285.
What is the Square Root of 2285?
The square root is the inverse of the square of a number. 2285 is not a perfect square. The square root of 2285 is expressed in both radical and exponential forms. In the radical form, it is expressed as √2285, whereas (2285)^(1/2) in the exponential form. √2285 ≈ 47.798, 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 2285
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 2285 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 2285 is broken down into its prime factors.
Step 1: Finding the prime factors of 2285 Breaking it down, we get 5 x 457. The factorization of 457 is 457 itself as it is a prime number.
Step 2: Since 2285 is not a perfect square, the digits of the number can’t be grouped in pairs.
Therefore, calculating √2285 using prime factorization alone is not feasible.
Square Root of 2285 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: Start by grouping the digits from right to left. For 2285, group it as 22 and 85.
Step 2: Find a number whose square is less than or equal to 22. This is 4, as 4 x 4 = 16. Subtract 16 from 22 to get 6, and bring down the next pair 85, making it 685.
Step 3: Double the divisor (4), getting 8, and find a digit n such that 8n x n is less than or equal to 685.
Step 4: Find n = 7, as 87 x 7 = 609. Subtract 609 from 685 to get 76.
Step 5: Add a decimal point and bring down 00 to make it 7600. Repeat the process.
Step 6: Continue the long division process to get a more accurate value.
Square Root of 2285 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 2285 using the approximation method.
Step 1: Find the closest perfect squares to 2285. 2025 (45²) and 2304 (48²) are the closest. √2285 falls between 45 and 48.
Step 2: Use interpolation to find the approximate value: (2285 - 2025) / (2304 - 2025) = (260 / 279).
This shows that √2285 is approximately midway, yielding an answer around 47.8.
Common Mistakes and How to Avoid Them in the Square Root of 2285
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 remind students that a number has 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 and then move on to the next step.
For example: √(12+24) = √12 + √24 is the wrong method. The right way 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 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 the 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. This may either happen in subtracting or elsewhere.
Square Root of 2285 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √2285?
The area of the square is approximately 5228.04 square units.
Explanation
The area of the square = side².
The side length is given as √2285.
Area of the square = side² = √2285 × √2285 ≈ 47.798 × 47.798 ≈ 2285.
Therefore, the area of the square box is approximately 5228.04 square units.
Problem 2
A square-shaped building measuring 2285 square feet is built; if each of the sides is √2285, what will be the square feet of half of the building?
1142.5 square feet
Explanation
We can simply divide the given area by 2 as the building is square-shaped. Dividing 2285 by 2 = 1142.5
Problem 3
Calculate √2285 × 5.
Approximately 238.99
Explanation
The first step is to find the square root of 2285, which is approximately 47.798, and then multiply 47.798 by 5.
So, 47.798 × 5 ≈ 238.99
Problem 4
What will be the square root of (2280 + 5)?
The square root is approximately 47.798
Explanation
To find the square root, we need to find the sum of (2280 + 5), which is 2285.
The square root of 2285 is approximately 47.798.
Problem 5
Find the perimeter of a rectangle if its length ‘l’ is √2285 units and the width ‘w’ is 38 units.
We find the perimeter of the rectangle as approximately 171.596 units.
Explanation
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√2285 + 38) ≈ 2 × (47.798 + 38) ≈ 2 × 85.798 ≈ 171.596 units.
