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, including vehicle design, finance, etc. Here, we will discuss the square root of 8000.

What is the Square Root of 8000?

The square root is the inverse of the square of the number. 8000 is not a perfect square. The square root of 8000 is expressed in both radical and exponential form. In the radical form, it is expressed as √8000, whereas (8000)^(1/2) in the exponential form. √8000 = 89.4427, 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 8000

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 8000 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 8000 is broken down into its prime factors.

Step 1: Finding the prime factors of 8000 Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 5 x 5 x 5: 2^5 x 5^3

Step 2: Now that we have found the prime factors of 8000, the second step is to make pairs of those prime factors. Since 8000 is not a perfect square, the digits of the number can’t be grouped in pairs completely. Therefore, calculating 8000 using prime factorization requires further calculation.

Square Root of 8000 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 8000, we need to group it as 80 and 00.

Step 2: Now we need to find n whose square is 64. We can say n as ‘8’ because 8 x 8 = 64, which is less than or equal to 80. Now the quotient is 8 after subtracting 80 - 64; the remainder is 16.

Step 3: Now let us bring down 00, which is the new dividend. Add the old divisor with the same number 8 + 8, we get 16, which will be our new divisor.

Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 16n as the new divisor, we need to find the value of n.

Step 5: The next step is finding 16n × n ≤ 1600. Let us consider n as 9, now 16 x 9 = 144

Step 6: Subtract 1600 from 144, the difference is 1600 - 144 = 1456, and the quotient is 89.

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 145600.

Step 8: Now we need to find the new divisor that is 178 because 178 x 8 = 1424

Step 9: Subtracting 1424 from 1456, we get the result 32.

Step 10: Now the quotient is 89.4

Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there are no decimal values, continue till the remainder is zero. So the square root of √8000 is approximately 89.44.

Square Root of 8000 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 8000 using the approximation method.

Step 1: Now we have to find the closest perfect square of √8000. The smallest perfect square less than 8000 is 7921, and the largest perfect square more than 8000 is 8100. √8000 falls somewhere between 89 and 90.

Step 2: Now we need to apply the formula that is (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) Going by the formula (8000 - 7921) ÷ (8100 - 7921) = 0.4427 Using the formula, we identified the decimal point of our square root. The next step is adding the value we got initially to the decimal number, which is 89 + 0.4427 = 89.4427, so the square root of 8000 is approximately 89.4427.

Common Mistakes and How to Avoid Them in the Square Root of 8000

Students do make mistakes while finding the square root, such as forgetting about the negative square root, skipping long division methods, etc. 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 √5000?

Okay, lets begin

The area of the square is 5000 square units.

Explanation

The area of the square = side². The side length is given as √5000. Area of the square = side² = √5000 x √5000 = 5000. Therefore, the area of the square box is 5000 square units.

Problem 2

A square-shaped building measuring 8000 square feet is built; if each of the sides is √8000, what will be the square feet of half of the building?

Okay, lets begin

4000 square feet

Explanation

We can just divide the given area by 2 as the building is square-shaped. Dividing 8000 by 2 = we get 4000. So half of the building measures 4000 square feet.

Problem 3

Calculate √8000 x 5.

Okay, lets begin

447.2135

Explanation

The first step is to find the square root of 8000, which is 89.4427. The second step is to multiply 89.4427 with 5. So 89.4427 x 5 = 447.2135.

Problem 4

What will be the square root of (5000 + 1000)?

Okay, lets begin

The square root is 90.5539.

Explanation

To find the square root, we need to find the sum of (5000 + 1000). 5000 + 1000 = 6000, and then √6000 = 77.4597. Therefore, the square root of (5000 + 1000) is approximately ±77.4597.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √5000 units and the width ‘w’ is 80 units.

Okay, lets begin

We find the perimeter of the rectangle as 357.2132 units.

Explanation

Perimeter of the rectangle = 2 × (length + width). Perimeter = 2 × (√5000 + 80) = 2 × (70.7107 + 80) = 2 × 150.7107 = 301.4214 units.
