Square Root of 796

Professor Greenline Explaining Math Concepts

If a number is multiplied by itself, the result is a square. The inverse of squaring a number is finding its square root. Square roots are used in fields like architecture, finance, and physics. Here, we will discuss the square root of 796.

What is the Square Root of 796?

The square root is the inverse operation of squaring a number. 796 is not a perfect square. The square root of 796 is expressed in both radical and exponential form. In the radical form, it is expressed as √796, whereas in exponential form, it is (796)^(1/2). √796 ≈ 28.215, which is an irrational number as it cannot be expressed as a simple fraction.

Finding the Square Root of 796

The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, the long division method and approximation method are used. Let us now learn these methods:

 

  • Prime factorization method
  • Long division method
  • Approximation method

Square Root of 796 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 796 is broken down into its prime factors.

 

Step 1: Finding the prime factors of 796 Breaking it down, we get 2 x 2 x 199. Since 199 is a prime number, 796 is expressed as 2² x 199.

 

Step 2: Now, we found out the prime factors of 796. Since 796 is not a perfect square, the digits of the number can’t be grouped into pairs, making it impossible to calculate the square root using prime factorization alone.

Square Root of 796 by Long Division Method

The long division method is particularly used for non-perfect square numbers. In this method, we try to find the closest perfect square number for the given number. Let us 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 796, we need to group it as 96 and 7.

 

Step 2: Now we need to find a number whose square is less than or equal to 7. We can take 2, as 2 x 2 = 4, which is less than 7. Now the quotient is 2. Subtracting 4 from 7 gives 3.

 

Step 3: Bring down 96 next to 3, making the new dividend 396. Double the previous quotient (2) to get 4, which will start our new divisor.

 

Step 4: Find a number, say n, such that 4n × n ≤ 396. We find n = 7 works because 47 x 7 = 329.

 

Step 5: Subtract 329 from 396 to get 67, and the quotient is now 27.

 

Step 6: Since the dividend is less than the divisor, we need to add a decimal point, which allows us to add two zeroes to the dividend. The new dividend is 6700.

 

Step 7: Find the next digit n such that (540 + n) × n ≤ 6700. We find n = 1 works because 541 x 1 = 541.

 

Step 8: Subtract 541 from 6700 to get 6159, and the quotient is now 28.1.

 

Step 9: Continue this process until the desired precision after the decimal is achieved.

 

So the square root of √796 is approximately 28.215.

Square Root of 796 by Approximation Method

The approximation method is another way to find square roots. It is an easy method to find the square root of a given number. Let us learn how to find the square root of 796 using the approximation method.

 

Step 1: Find the closest perfect squares around 796.

 

The smallest perfect square less than 796 is 784 (which is 28²), and the largest perfect square greater than 796 is 841 (which is 29²). √796 falls between 28 and 29.

 

Step 2: Now apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) (796 - 784) / (841 - 784) = 12 / 57 ≈ 0.21

 

Add this to the base square root value of 28 to get approximately 28.21.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It's important to remember that a number has both positive and negative square roots. However, we often use only the positive square root, as it is typically the required one.

For example: √49 = ±7, but the negative root is often overlooked.

Problem 1

Can you help Max find the area of a square box if its side length is given as √796?

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

The area of the square is 796 square units.

Explanation

The area of the square = side².

The side length is given as √796.

Area of the square = side² = √796 x √796 = 796.

Therefore, the area of the square box is 796 square units.

Problem 2

A square-shaped building measuring 796 square feet is built; if each of the sides is √796, what will be the square feet of half of the building?

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

398 square feet

Explanation

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

Dividing 796 by 2, we get 398.

So half of the building measures 398 square feet.

Problem 3

Calculate √796 x 5.

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

141.075

Explanation

First, find the square root of 796, approximately 28.215.

Then multiply 28.215 by 5.

So 28.215 x 5 = 141.075.

Problem 4

What will be the square root of (796 + 4)?

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

The square root is 28.3.

Explanation

To find the square root, first find the sum of (796 + 4). 796 + 4 = 800, and then √800 ≈ 28.3.

Therefore, the square root of (796 + 4) is approximately ±28.3.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √796 units and the width ‘w’ is 50 units.

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

We find the perimeter of the rectangle as 156.43 units.

Explanation

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

Perimeter = 2 × (√796 + 50) = 2 × (28.215 + 50) = 2 × 78.215 = 156.43 units.
