Square Root of 2049
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 such as vehicle design, finance, etc. Here, we will discuss the square root of 2049.
What is the Square Root of 2049?
The square root is the inverse of the square of the number. 2049 is not a perfect square. The square root of 2049 is expressed in both radical and exponential form. In radical form, it is expressed as √2049, whereas (2049)^(1/2) in exponential form. √2049 ≈ 45.251, 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 2049
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 and approximation methods are used. Let us now learn the following methods.
- Prime factorization method
- Long division method
- Approximation method
Square Root of 2049 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 2049 is broken down into its prime factors.
Step 1: Finding the prime factors of 2049
Breaking it down, we get 3 x 683. 683 is a prime number. Therefore, the prime factorization of 2049 is 3 x 683.
Step 2: Since 2049 is not a perfect square, calculating 2049 using prime factorization does not yield a convenient result.
Square Root of 2049 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 numbers 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 2049, we need to group it as 49 and 20.
Step 2: Now, 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. Subtract 16 from 20, leaving a remainder of 4.
Step 3: Bring down 49, making the new dividend 449.
Step 4: Double the previous quotient 4, giving us 8, which will be part of our new divisor.
Step 5: Find a digit x such that 8x x is less than or equal to 449. Here, x is 5 because 85 x 5 = 425.
Step 6: Subtract 425 from 449, leaving a remainder of 24.
Step 7: Since the remainder is less than the divisor, add a decimal point and bring down 00, making the new dividend 2400.
Step 8: Find a digit y such that 905y x y is less than or equal to 2400.
Step 9: Continue the process to find the quotient up to the desired decimal places.
So the square root of √2049 is approximately 45.251.
Square Root of 2049 by Approximation Method
The approximation method is another method for finding the 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 2049 using the approximation method.
Step 1: Find the closest perfect squares of √2049. The smaller perfect square is 2025 (45²), and the larger perfect square is 2116 (46²). √2049 falls somewhere between 45 and 46.
Step 2: Now we need to apply the formula: (Given number - smaller perfect square) / (Larger perfect square - smaller perfect square).
Using the formula: (2049 - 2025) / (2116 - 2025) = 0.251. Adding this decimal value to the smaller integer, we get 45 + 0.251 = 45.251, so the square root of 2049 is approximately 45.251.
Common Mistakes and How to Avoid Them in the Square Root of 2049
Students often make mistakes while finding the square root, such as forgetting about the negative square root and skipping long division methods. Let us look at a few of these mistakes in detail.
Mistake 1
Forgetting about the negative square root
It is important to make students aware that a number has both positive and negative square roots. However, we usually consider 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.
Square Root of 2049 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √2049?
The area of the square is approximately 4198.601 square units.
Explanation
The area of the square = side².
The side length is given as √2049.
Area of the square = side² = √2049 × √2049 ≈ 45.251 × 45.251 ≈ 2049.
Therefore, the area of the square box is approximately 4198.601 square units.
Problem 2
A square-shaped building measuring 2049 square feet is built; if each side is √2049, what will be the square feet of half of the building?
1024.5 square feet
Explanation
We can divide the given area by 2 since the building is square-shaped.
Dividing 2049 by 2, we get 1024.5.
So, half of the building measures 1024.5 square feet.
Problem 3
Calculate √2049 × 5.
Approximately 226.255
Explanation
The first step is to find the square root of 2049, which is approximately 45.251.
The second step is to multiply 45.251 by 5.
So, 45.251 × 5 ≈ 226.255.
Problem 4
What will be the square root of (2049 + 7)?
The square root is approximately 46.
Explanation
To find the square root, we need to find the sum of (2049 + 7). 2049 + 7 = 2056.
The square root of 2056 is approximately 45.34, which rounds to 46.
Therefore, the square root of (2049 + 7) is approximately ±46.
Problem 5
Find the perimeter of the rectangle if its length ‘l’ is √2049 units and the width ‘w’ is 50 units.
The perimeter of the rectangle is approximately 190.502 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√2049 + 50) ≈ 2 × (45.251 + 50) ≈ 2 × 95.251 ≈ 190.502 units.
