Square Root of 694

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 694.

What is the Square Root of 694?

The square root is the inverse of the square of the number. 694 is not a perfect square. The square root of 694 is expressed in both radical and exponential form. In the radical form, it is expressed as √694, whereas 694^(1/2) in the exponential form. √694 ≈ 26.342, 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 694

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 694 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 694 is broken down into its prime factors.

 

Step 1: Finding the prime factors of 694

 

Breaking it down, we get 2 x 347. 694 = 2^1 x 347^1

 

Step 2: Now we found out the prime factors of 694. The second step is to make pairs of those prime factors. Since 694 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating 694 using prime factorization is not feasible for finding its square root.

Square Root of 694 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 694, we write it as 6 and 94.

 

Step 2: Now, find n whose square is less than or equal to 6. We take n as ‘2’ because 2 x 2 = 4, which is less than 6. The quotient is 2, and after subtracting 4 from 6, the remainder is 2.

 

Step 3: Bring down 94, making the new dividend 294. Add the old divisor with the same number, 2 + 2, to get 4, which will be our new divisor.

 

Step 4: The new divisor will be the sum of the previous quotient and double it. We have 4n as the new divisor; we need to find n such that 4n x n ≤ 294.

 

Step 5: Let n be 6, so 46 x 6 = 276, which is less than 294.

 

Step 6: Subtract 276 from 294; the difference is 18, and the quotient becomes 26.

 

Step 7: 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 1800.

 

Step 8: Now find the new divisor, which is 526. When 526 is multiplied by 3, we get 1578.

 

Step 9: Subtracting 1578 from 1800 gives us 222.

 

Step 10: The quotient so far is 26.3.

 

Step 11: Continue these steps until we get two decimal places or until the remainder is zero.

 

So the square root of √694 is approximately 26.34.

Square Root of 694 by Approximation Method

The approximation method is another method for finding 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 694 using the approximation method.

 

Step 1: Find the closest perfect squares around √694. The smallest perfect square less than 694 is 676, and the largest perfect square greater than 694 is 729. √694 falls somewhere between 26 and 27.

 

Step 2: Apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) (694 - 676) / (729 - 676) = 18 / 53 ≈ 0.34 Using the formula, we identified the decimal point of our square root. Adding this to the whole number gives us 26 + 0.34 = 26.34, so the square root of 694 is approximately 26.34.

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: √50 ≈ 7.07, there is also -7.07 which should not be forgotten.

Problem 1

Can you help Max find the area of a square box if its side length is given as √694?

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

The area of the square is approximately 694 square units.

Explanation

The area of the square = side^2. The side length is given as √694.

Area of the square = side^2 = √694 x √694 = 694.

Therefore, the area of the square box is approximately 694 square units.

Problem 2

A square-shaped building measuring 694 square feet is built; if each of the sides is √694, what will be the square feet of half of the building?

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

347 square feet

Explanation

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

Dividing 694 by 2, we get 347.

So half of the building measures 347 square feet.

Problem 3

Calculate √694 x 5.

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

131.71

Explanation

The first step is to find the square root of 694, which is approximately 26.34.

The second step is to multiply 26.34 by 5.

So 26.34 x 5 = 131.71.

Problem 4

What will be the square root of (694 + 6)?

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

The square root is approximately 26.

Explanation

To find the square root, we need to find the sum of (694 + 6). 694 + 6 = 700, and then √700 ≈ 26.46.

Therefore, the square root of (694 + 6) is approximately ±26.46.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √694 units and the width ‘w’ is 38 units.

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

The perimeter of the rectangle is approximately 128.68 units.

Explanation

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

Perimeter = 2 × (√694 + 38) = 2 × (26.34 + 38) = 2 × 64.34 = 128.68 units.
