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 7569.

What is the Square Root of 7569?

The square root is the inverse of the square of the number. 7569 is a perfect square. The square root of 7569 is expressed in both radical and exponential form. In the radical form, it is expressed as √7569, whereas (7569)^(1/2) in exponential form. √7569 = 87, 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 7569

The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, methods like 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 7569 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 7569 is broken down into its prime factors.

Step 1: Finding the prime factors of 7569 Breaking it down, we get 3 x 3 x 29 x 29: 3² x 29²

Step 2: Now we found out the prime factors of 7569. The second step is to make pairs of those prime factors. Since 7569 is a perfect square, we can pair the prime factors. Therefore, calculating √7569 using prime factorization yields 87 (since 3 x 29 = 87).

Square Root of 7569 by Long Division Method

The long division method can also be used for finding the square root of a perfect square. 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 7569, we group it as 75 and 69.

Step 2: Now we need to find n whose square is less than or equal to 75. We can say n is '8' because 8 x 8 = 64, which is less than 75. Now the quotient is 8, and after subtracting 75 - 64, the remainder is 11.

Step 3: Now let us bring down 69, which is the new dividend. Add the old divisor with the same number 8 + 8, we get 16, which will be our new divisor.

Step 4: The new divisor will be 16n. We need to find the value of n.

Step 5: The next step is finding 16n × n ≤ 1169. Let us consider n as 7, now 167 × 7 = 1169.

Step 6: Subtract 1169 from 1169, and the remainder is 0, and the quotient is 87. So the square root of √7569 is 87.

Square Root of 7569 by Approximation Method

Approximation method is generally used for non-perfect squares, but here's how we can confirm the square root of 7569 using this method.

Step 1: Now, we have to find the closest perfect squares around √7569. The smallest perfect square close to 7569 is 7225, and the largest perfect square is 7744. √7569 falls somewhere between 85 and 88.

Step 2: Now, we need to apply the approximation method, which involves checking values in this range. Since 87² = 7569, we confirm that 87 is the square root of 7569.

Common Mistakes and How to Avoid Them in the Square Root of 7569

Students do make mistakes while finding the square root, such as forgetting about the negative square root or skipping steps in the long division method. Now let us look at a few of those mistakes that students tend to make in detail.

Problem 1

Can you help Max find the area of a square box if its side length is given as √3600?

Okay, lets begin

The area of the square is 3600 square units.

Explanation

The area of the square = side². The side length is given as √3600, which equals 60. Area of the square = side² = √3600 x √3600 = 60 x 60 = 3600. Therefore, the area of the square box is 3600 square units.

Problem 2

A square-shaped building measuring 7569 square feet is built; if each of the sides is √7569, what will be the square feet of half of the building?

Okay, lets begin

3784.5 square feet

Explanation

We can just divide the given area by 2 as the building is square-shaped. Dividing 7569 by 2 = 3784.5. So half of the building measures 3784.5 square feet.

Problem 3

Calculate √7569 x 4.

Okay, lets begin

348

Explanation

The first step is to find the square root of 7569, which is 87. The second step is to multiply 87 by 4. So 87 x 4 = 348.

Problem 4

What will be the square root of (3600 + 1681)?

Okay, lets begin

The square root is 93.

Explanation

To find the square root, we need to find the sum of (3600 + 1681). 3600 + 1681 = 5281, and then √5281 = 93. Therefore, the square root of (3600 + 1681) is ±93.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √7569 units and the width ‘w’ is 38 units.

Okay, lets begin

We find the perimeter of the rectangle as 250 units.

Explanation

Perimeter of the rectangle = 2 × (length + width). Perimeter = 2 × (√7569 + 38) = 2 × (87 + 38) = 2 × 125 = 250 units.
