Square Root of 2809

Professor Greenline Explaining Math Concepts

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 2809.

What is the Square Root of 2809?

The square root is the inverse of the square of the number. 2809 is a perfect square. The square root of 2809 is expressed in both radical and exponential form. In the radical form, it is expressed as √2809, whereas 2809^(1/2) in the exponential form. √2809 = 53, which is a rational number because it can be expressed in the form of p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 2809

The prime factorization method is used for perfect square numbers. Let us now learn the following methods:

 

  • Prime factorization method
  • Long division method

Square Root of 2809 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 2809 is broken down into its prime factors.

 

Step 1: Finding the prime factors of 2809 Breaking it down, we get 53 x 53: 53^2

 

Step 2: Now we found out the prime factors of 2809. Since 2809 is a perfect square, we can group the prime factors in pairs.

 

Therefore, the square root of 2809 using prime factorization is 53.

Square Root of 2809 by Long Division Method

The long division method is particularly used for non-perfect square numbers as well, but it can be applied to perfect squares for verification. 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 pairing the digits from right to left. In the case of 2809, we pair it as 28 and 09.

 

Step 2: Find the largest number whose square is less than or equal to the first pair (28). That number is 5 because 5 x 5 = 25, and 25 is less than 28.

 

Step 3: Subtract 25 from 28, leaving a remainder of 3. Bring down the next pair of digits (09) to make it 309.

 

Step 4: Double the divisor (5), which gives 10.

 

Step 5: Find a digit (n) such that 10n x n is less than or equal to 309. That digit is 3, because 103 x 3 = 309.

 

Step 6: Subtract 309 from 309, leaving a remainder of 0.

 

Step 7: The quotient 53 is the square root of 2809.

Forgetting about the negative square root

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

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, √2809 = 53, there is also -53 which should not be forgotten.

Square Root of 2809 Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

Can you help Max find the area of a square box if its side length is given as √2809?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of the square is 2809 square units.

Explanation

The area of the square = side².

The side length is given as √2809.

Area of the square = side²

= √2809 x √2809

= 53 × 53

= 2809.

Therefore, the area of the square box is 2809 square units.

Problem 2

A square-shaped building measuring 2809 square feet is built; if each of the sides is √2809, what will be the square feet of half of the building?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

1404.5 square feet

Explanation

We can just divide the given area by 2 as the building is square-shaped.

Dividing 2809 by 2 = we get 1404.5.

So half of the building measures 1404.5 square feet.

Problem 3

Calculate √2809 x 5.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

265

Explanation

The first step is to find the square root of 2809, which is 53.

The second step is to multiply 53 by 5.

So 53 x 5 = 265.

Problem 4

What will be the square root of (2500 + 309)?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The square root is 53.

Explanation

To find the square root, we need to find the sum of (2500 + 309).

2500 + 309 = 2809, and then √2809 = 53.

Therefore, the square root of (2500 + 309) is ±53.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √2809 units and the width ‘w’ is 10 units.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

We find the perimeter of the rectangle as 126 units.

Explanation

Perimeter of the rectangle = 2 × (length + width)

Perimeter = 2 × (√2809 + 10)

= 2 × (53 + 10)

= 2 × 63

= 126 units.
