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 such as engineering, physics, and finance. Here, we will discuss the square root of 15600.

What is the Square Root of 15600?

The square root is the inverse of the square of the number. 15600 is not a perfect square. The square root of 15600 is expressed in both radical and exponential form. In the radical form, it is expressed as √15600, whereas (15600)(1/2) in the exponential form. √15600 ≈ 124.899, 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 15600

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: -

  1. Prime factorization method 
  2. Long division method 
  3. Approximation method

Square Root of 15600 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 15600 is broken down into its prime factors.

Step 1: Finding the prime factors of 15600 Breaking it down, we get 2 × 2 × 2 × 2 × 3 × 5 × 5 × 13: 24 × 31 × 52 × 131

Step 2: Now that we have found the prime factors of 15600, the next step is to make pairs of those prime factors. Since 15600 is not a perfect square, the digits of the number can’t be grouped entirely into pairs.

Therefore, calculating 15600 using prime factorization is not straightforward.

Square Root of 15600 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 15600, we need to group it as 00, 56, and 15.

Step 2: Now, find n whose square is less than or equal to 15. We can say n is ‘3’ because 3 × 3 = 9, which is less than 15. Subtract 9 from 15 to get a remainder of 6. The quotient is 3.

Step 3: Bring down 56 to make the new dividend 656. Add the old divisor (3) to itself to get 6, which becomes the new divisor.

Step 4: Multiply the new divisor (6) by a number p such that 6p × p ≤ 656. The suitable value for p is 10 since 610 × 0 = 6100, which is less than 656.

Step 5: Subtract 6100 from 65600 to get a remainder of 4600.

Step 6: Bring down the next pair of zeroes to make the new dividend 460000. Add 10 to the previous divisor to make it 620.

Step 7: Find a new digit q such that 620q × q ≤ 460000. The suitable value for q is 7 since 6207 × 7 = 43449, which is less than 460000.

Step 8: Subtract 43449 from 460000 to get a remainder of 25551.

Step 9: Continue this process until you achieve the desired level of accuracy. The quotient obtained is approximately 124.899.

Square Root of 15600 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. Now let us learn how to find the square root of 15600 using the approximation method.

Step 1: First, find the closest perfect square to √15600. The closest perfect squares are 14400 (1202) and 16900 (1302). √15600 falls between 120 and 130.

Step 2: Now, apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square).

Applying the formula, (15600 - 14400) ÷ (16900 - 14400) = 1200 ÷ 2500 = 0.48. Adding this to the lower limit, 120 + 0.48 ≈ 124.48, so the approximate square root of 15600 is 124.48.

Common Mistakes and How to Avoid Them in the Square Root of 15600

Students often make mistakes while finding the square root, such as forgetting about the negative square root or skipping steps in the long division method. Let us look at a few of those mistakes in detail.

Problem 1

Can you help Max find the area of a square box if its side length is given as √15600?

Okay, lets begin

The area of the square is 15600 square units.

Explanation

The area of the square = side2.

The side length is given as √15600.

Area of the square = side2 = √15600 × √15600 = 15600.

Therefore, the area of the square box is 15600 square units.

Problem 2

A square-shaped building measuring 15600 square feet is built; if each of the sides is √15600, what will be the square feet of half of the building?

Okay, lets begin

7800 square feet

Explanation

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

Dividing 15600 by 2, we get 7800.

So half of the building measures 7800 square feet.

Problem 3

Calculate √15600 × 5.

Okay, lets begin

624.495

Explanation

The first step is to find the square root of 15600, which is approximately 124.899.

The second step is to multiply 124.899 by 5.

So 124.899 × 5 = 624.495.

Problem 4

What will be the square root of (10000 + 5600)?

Okay, lets begin

The square root is 130.

Explanation

To find the square root,

we need to find the sum of (10000 + 5600).

10000 + 5600 = 15600, and then √15600 ≈ 124.899.

Therefore, the square root of (10000 + 5600) is approximately ±124.899.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √15600 units and the width ‘w’ is 50 units.

Okay, lets begin

We find the perimeter of the rectangle as 449.798 units.

Explanation

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

Perimeter = 2 × (√15600 + 50) = 2 × (124.899 + 50) = 2 × 174.899 = 449.798 units.
