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 6.76.

What is the Square Root of 6.76?

The square root is the inverse of the square of the number. 6.76 is a perfect square. The square root of 6.76 is expressed in both radical and exponential form. In radical form, it is expressed as √6.76, whereas (6.76)^(1/2) in exponential form. √6.76 = 2.6, 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 6.76

The prime factorization method is used for perfect square numbers. For non-perfect square numbers, other methods like long-division and approximation are used. Let us now learn the following methods:

  • Prime factorization method
  • Long division method
  • Approximation method

Square Root of 6.76 by Prime Factorization Method

The product of prime factors is the prime factorization of a number.

Now let us look at how 6.76 is broken down into its prime factors.

Since 6.76 is a perfect square, we can write it as (2.6)^2.

Therefore, √6.76 = 2.6.

Square Root of 6.76 by Long Division Method

The long division method is particularly used for non-perfect square numbers but can also be applied for precision. However, since 6.76 is already a perfect square, we know its square root is 2.6.

Square Root of 6.76 by Approximation Method

The approximation method is another method for finding square roots and is useful for non-perfect squares. However, since 6.76 is a perfect square, we directly know that √6.76 = 2.6.

Common Mistakes and How to Avoid Them in the Square Root of 6.76

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 √7?

Okay, lets begin

The area of the square is approximately 49 square units.

Explanation

The area of the square = side^2.

The side length is given as √7.

Area of the square = side^2 = √7 × √7 ≈ 2.64575 × 2.64575 ≈ 7.

Therefore, the area of the square box is approximately 7 square units.

Problem 2

A square-shaped building measuring 6.76 square feet is built; if each of the sides is √6.76, what will be the square feet of half of the building?

Okay, lets begin

3.38 square feet

Explanation

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

Dividing 6.76 by 2 = we get 3.38.

So half of the building measures 3.38 square feet.

Problem 3

Calculate √6.76 × 5.

Okay, lets begin

13

Explanation

The first step is to find the square root of 6.76, which is 2.6.

The second step is to multiply 2.6 by 5. So, 2.6 × 5 = 13.

Well explained 👍

Problem 4

What will be the square root of (4 + 2.76)?

Okay, lets begin

The square root is 2.6.

Explanation

To find the square root, we need to find the sum of (4 + 2.76). 4 + 2.76 = 6.76, and then √6.76 = 2.6.

Therefore, the square root of (4 + 2.76) is ±2.6.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √6.76 units and the width ‘w’ is 8 units.

Okay, lets begin

The perimeter of the rectangle is 21.2 units.

Explanation

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

Perimeter = 2 × (√6.76 + 8) = 2 × (2.6 + 8) = 2 × 10.6 = 21.2 units.
