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 160000.

What is the Square Root of 160000?

The square root is the inverse of the square of the number. 160000 is a perfect square. The square root of 160000 is expressed in both radical and exponential form. In the radical form, it is expressed as √160000, whereas (160000)^(1/2) in the exponential form. √160000 = 400, which is a rational number because it can be expressed in the form of p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 160000

The prime factorization method is used for perfect square numbers. For perfect squares like 160000, both the prime factorization method and the long division method can be used. Let us now learn the following methods:

  • Prime factorization method 
     
  • Long division method

Square Root of 160000 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 160000 is broken down into its prime factors.

Step 1: Finding the prime factors of 160000. Breaking it down, we get 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5: 2^6 × 5^4

Step 2: Now we found out the prime factors of 160000. The second step is to make pairs of those prime factors. Since 160000 is a perfect square, the digits of the number can be grouped in pairs. Therefore, calculating √160000 using prime factorization is possible.

Step 3: The square root is obtained by taking one number from each pair, so √160000 = 2^3 × 5^2 = 8 × 25 = 200.

Square Root of 160000 by Long Division Method

The long division method is particularly useful for both perfect and 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 160000, we group it as 16 and 0000.

Step 2: Now we need to find n whose square is less than or equal to 16. We can say n is 4 because 4 × 4 = 16. Now the quotient is 4, and the remainder is 0.

Step 3: Bring down the next pair of zeros, making the new dividend 0000, and bring down another pair making it 000000.

Step 4: The divisor is now 80 (2 × 40) and bringing down the 0s does not change anything as they are zeros. Step 5: Therefore, √160000 = 400.

Approximating the Square Root of 160000

For a perfect square like 160000, approximation is not needed, but if the number were not a perfect square, approximation methods could be used.

Common Mistakes and How to Avoid Them in the Square Root of 160000

Students do make mistakes while finding the square root, like forgetting about the negative square root or skipping 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 √160000?

Okay, lets begin

The area of the square is 160000 square units.

Explanation

The area of a square = side^2.

The side length is given as √160000.

Area of the square = side^2 = √160000 × √160000 = 400 × 400 = 160000

Therefore, the area of the square box is 160000 square units.

Problem 2

A square-shaped building measuring 160000 square feet is built; if each of the sides is √160000, what will be the square feet of half of the building?

Okay, lets begin

80000 square feet

Explanation

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

Dividing 160000 by 2 = 80000

So half of the building measures 80000 square feet.

Problem 3

Calculate √160000 × 5.

Okay, lets begin

2000

Explanation

The first step is to find the square root of 160000, which is 400. The second step is to multiply 400 by 5. So 400 × 5 = 2000.

Problem 4

What will be the square root of (160000 + 40000)?

Okay, lets begin

The square root is 447.21

Explanation

To find the square root, we need to find the sum of (160000 + 40000) 160000 + 40000 = 200000, and then √200000 ≈ 447.21. Therefore, the square root of (160000 + 40000) is approximately ±447.21.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √160000 units and the width ‘w’ is 200 units.

Okay, lets begin

We find the perimeter of the rectangle as 1200 units.

Explanation

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

Perimeter = 2 × (√160000 + 200) = 2 × (400 + 200) = 2 × 600 = 1200 units.
