Square Root of 1517

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 fields such as vehicle design, finance, etc. Here, we will discuss the square root of 1517.

What is the Square Root of 1517?

The square root is the inverse of the square of a number. 1517 is not a perfect square. The square root of 1517 is expressed in both radical and exponential form. In radical form, it is expressed as √1517, whereas (1517)^(1/2) is the exponential form. √1517 ≈ 38.9504, 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 1517

The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers, where long-division and approximation methods are used. Let us now learn the following methods:

 

  • Prime factorization method
  • Long division method
  • Approximation method

Square Root of 1517 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 1517 is broken down into its prime factors.

 

Step 1: Finding the prime factors of 1517 Breaking it down, we get 1517 = 37 x 41.

 

Step 2: Now that we have found the prime factors of 1517, we realize that since 1517 is not a perfect square, the digits of the number can’t be grouped into pairs.

 

Therefore, calculating 1517 using prime factorization alone is not feasible.

Professor Greenline from BrightChamps

Square Root of 1517 by Long Division Method

The long division method is particularly used for non-perfect square numbers. In this method, we check for the closest perfect square number to 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 1517, we group it as 15 and 17.

 

Step 2: Now, we need to find n whose square is less than or equal to 15. We can say n is ‘3’ because 3 x 3 = 9, which is less than 15. Now, the quotient is 3, and after subtracting 9 from 15, the remainder is 6.

 

Step 3: Now, let us bring down 17, making the new dividend 617. Add the old divisor with itself, 3 + 3, which gives us 6 as the new divisor.

 

Step 4: The new divisor will be 6n. We need to find the value of n such that 6n x n ≤ 617. Let us consider n as 9, then 69 x 9 = 621.

 

Step 5: Subtract 621 from 617, the difference is -4, but since this is incorrect, we adjust n to 8, so 68 x 8 = 544.

 

Step 6: Subtract 544 from 617, the difference is 73, and the quotient is 38.

 

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 7300.

 

Step 8: Now, we need to find the new divisor, which is 389, because 389 x 9 = 3501.

 

Step 9: Subtracting 3501 from 7300 gives the result 3799.

 

Step 10: Now, the quotient is 38.9.

 

Step 11: Continue these steps until we get two numbers after the decimal point. If there are no decimal values, continue until the remainder is zero.

 

So the square root of √1517 is approximately 38.95.

Square Root of 1517 by Approximation Method

The approximation method is another method for finding square roots, and 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 1517 using the approximation method.

 

Step 1: We have to find the closest perfect squares to √1517.

 

The smallest perfect square less than 1517 is 1521, and the largest perfect square close to 1517 is 1600. √1517 falls somewhere between 38 and 40.

 

Step 2: Now, we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula (1517 - 1521) / (1600 - 1521) = -4 / 79 ≈ -0.0506.

 

Using the formula, we identified the adjustment to the nearest lower perfect square root. The next step is adjusting the value we got initially to the decimal number: 39 - 0.05 ≈ 38.95, so the square root of 1517 is approximately 38.95.

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.

Square Root of 1517 Examples

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

Can you help Max find the area of a square box if its side length is given as √1517?

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

The area of the square is 1517 square units.

Explanation

The area of the square = side^2.

The side length is given as √1517.

Area of the square = side^2 = √1517 x √1517 = 1517.

Therefore, the area of the square box is 1517 square units.

Problem 2

A square-shaped building measuring 1517 square feet is built; if each of the sides is √1517, what will be the square feet of half of the building?

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

758.5 square feet

Explanation

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

Dividing 1517 by 2 = we get 758.5.

So half of the building measures 758.5 square feet.

Problem 3

Calculate √1517 x 5.

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

194.752

Explanation

The first step is to find the square root of 1517, which is approximately 38.95.

The second step is to multiply 38.95 by 5.

So 38.95 x 5 ≈ 194.752.

Problem 4

What will be the square root of (1517 + 9)?

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

The square root is 39.

Explanation

To find the square root, we need to find the sum of (1517 + 9). 1517 + 9 = 1526, and then √1526 ≈ 39.

Therefore, the square root of (1517 + 9) is approximately ±39.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √1517 units and the width ‘w’ is 38 units.

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

We find the perimeter of the rectangle as 153.9 units.

Explanation

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

Perimeter = 2 × (√1517 + 38) = 2 × (38.95 + 38) ≈ 2 × 76.95 ≈ 153.9 units.
