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 vehicle design, finance, etc. Here, we will discuss the square root of 16000.

What is the Square Root of 16000?

The square root is the inverse of the square of a number. 16000 is not a perfect square. The square root of 16000 is expressed in both radical and exponential form. In the radical form, it is expressed as √16000, whereas (16000)(1/2) in the exponential form. √16000 ≈ 126.4911, 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 16000

The prime factorization method is used for perfect square numbers. However, the prime factorization method is not typically 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 16000 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 16000 is broken down into its prime factors.

Step 1: Finding the prime factors of 16000 Breaking it down, we get 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5: 26 × 54

Step 2: Now that we have found the prime factors of 16000, the next step is to make pairs of those prime factors. Since 16000 is not a perfect square, the digits of the number can’t be grouped entirely into pairs.

Therefore, calculating 16000 using prime factorization yields √(26 × 54) = 23 × 52 × √(2 × 5) = 100 × √10.

Square Root of 16000 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 group the numbers from right to left. In the case of 16000, we group it as 16 and 000.

Step 2: Now we need to find n whose square is 16. We can say n as '4' because 4 × 4 is equal to 16. Now the quotient is 4, after subtracting 16-16 the remainder is 0.

Step 3: Now let us bring down 000, which is the new dividend. Add the old divisor with the same number 4 + 4, we get 8 which will be our new divisor.

Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 80n as the new divisor, we need to find the value of n.

Step 5: The next step is finding 80n × n ≤ 000. Since the dividend is 000, we proceed with adding decimal places to continue the division.

Step 6: Adding decimal places allows us to bring down more zeroes. Continue the division process to find more decimal places in the quotient. So the square root of √16000 ≈ 126.491.

Square Root of 16000 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 16000 using the approximation method.

Step 1: Now we have to find the closest perfect squares of √16000. The smallest perfect square less than 16000 is 14400 (1202) and the largest perfect square more than 16000 is 16900 (1302). √16000 falls somewhere between 120 and 130.

Step 2: Now we need to apply the formula that is (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square).

Using the formula (16000 - 14400) / (16900 - 14400) = 1600 / 2500 = 0.64. Using this, we identify the decimal point of our square root.

The next step is adding the value we got initially to the decimal number which is 120 + 0.64 ≈ 126.49, so the square root of 16000 is approximately 126.49.

Common Mistakes and How to Avoid Them in the Square Root of 16000

Students do make mistakes while finding square roots, such as forgetting about the negative square root or skipping steps in methods like the long division method. 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 √16000?

Okay, lets begin

The area of the square is 16000 square units.

Explanation

The area of the square = side².

The side length is given as √16000.

Area of the square = side² = (√16000) × (√16000) = 16000 square units.

Problem 2

A square-shaped building measuring 16000 square feet is built; if each of the sides is √16000, what will be the square feet of half of the building?

Okay, lets begin

8000 square feet.

Explanation

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

Dividing 16000 by 2 gives us 8000.

So half of the building measures 8000 square feet.

Problem 3

Calculate √16000 × 5.

Okay, lets begin

Approximately 632.455.

Explanation

The first step is to find the square root of 16000, which is approximately 126.491.

The second step is to multiply 126.491 by 5.

So 126.491 × 5 ≈ 632.455.

Problem 4

What will be the square root of (16000 + 400)?

Okay, lets begin

The square root is approximately 130.

Explanation

To find the square root,

we need to find the sum of (16000 + 400). 16000 + 400 = 16400,

and then the square root of 16400 is approximately 128.062.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √16000 units and the width ‘w’ is 38 units.

Okay, lets begin

The perimeter of the rectangle is approximately 328.982 units.

Explanation

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

Perimeter = 2 × (√16000 + 38) = 2 × (126.491 + 38) ≈ 2 × 164.491 ≈ 328.982 units.
