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 various fields like vehicle design, finance, etc. Here, we will discuss the square root of 7361.

What is the Square Root of 7361?

The square root is the inverse of the square of a number. 7361 is not a perfect square. The square root of 7361 is expressed in both radical and exponential form. In the radical form, it is expressed as √7361, whereas 7361^(1/2) in the exponential form. √7361 ≈ 85.792, 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 7361

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 7361 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 7361 is broken down into its prime factors.

Step 1: Finding the prime factors of 7361 Breaking it down, we get 13 x 13 x 43: 13^2 x 43

Step 2: Now that we found the prime factors of 7361, the second step is to make pairs of those prime factors. Since 7361 is not a perfect square, the digits of the number can’t be grouped into pairs. Therefore, calculating 7361 using prime factorization is impossible.

Square Root of 7361 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 7361, we need to group it as 73 and 61.

Step 2: Now we need to find n whose square is less than or equal to 73. We can say n as ‘8’ because 8 x 8 = 64, which is less than 73. After subtracting 73 - 64, the remainder is 9, and the quotient is 8.

Step 3: Now let us bring down 61, 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 160. Now we need to find a digit n such that 160n x n ≤ 961. Let us take n = 5, then 1605 x 5 = 8025.

Step 5: Subtract 961 - 8025, the difference is 1596.

Step 6: 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 159600.

Step 7: We repeat the process to calculate the next digits after the decimal. So the square root of √7361 ≈ 85.792

Square Root of 7361 by Approximation Method

The approximation method is another way to find 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 7361 using the approximation method.

Step 1: Now we have to find the closest perfect square to √7361. The smallest perfect square greater than 7361 is 7396, and the largest perfect square less than 7361 is 7225. √7361 falls somewhere between 85 and 86.

Step 2: Now we need to apply the formula that is (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula (7361 - 7225) ÷ (7396 - 7225) ≈ 0.792 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 85 + 0.792 ≈ 85.792, so the square root of 7361 is approximately 85.792.

Common Mistakes and How to Avoid Them in the Square Root of 7361

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.

Problem 1

Can you help Max find the area of a square box if its side length is given as √7361?

Okay, lets begin

The area of the square is 7361 square units.

Explanation

The area of the square = side^2. The side length is given as √7361. Area of the square = side^2 = √7361 x √7361 = 7361. Therefore, the area of the square box is 7361 square units.

Problem 2

A square-shaped field measuring 7361 square feet is built; if each of the sides is √7361, what will be the square feet of half of the field?

Okay, lets begin

3680.5 square feet

Explanation

We can just divide the given area by 2 as the field is square-shaped. Dividing 7361 by 2 = we get 3680.5 So half of the field measures 3680.5 square feet.

Problem 3

Calculate √7361 x 5.

Okay, lets begin

428.96

Explanation

The first step is to find the square root of 7361, which is approximately 85.792. The second step is to multiply 85.792 by 5. So 85.792 x 5 ≈ 428.96.

Problem 4

What will be the square root of (7361 + 39)?

Okay, lets begin

The square root is approximately 86.

Explanation

To find the square root, we need to find the sum of (7361 + 39). 7361 + 39 = 7400, and then √7400 ≈ 86. Therefore, the square root of (7361 + 39) is approximately ±86.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √7361 units and the width ‘w’ is 38 units.

Okay, lets begin

We find the perimeter of the rectangle as 247.584 units.

Explanation

Perimeter of the rectangle = 2 × (length + width) Perimeter = 2 × (√7361 + 38) = 2 × (85.792 + 38) = 2 × 123.792 = 247.584 units.
