If a number is multiplied by itself, the result is a square. The inverse of the square is a square root. The square root is used in fields such as engineering, mathematics, and physics. Here, we will discuss the square root of 16/3.

What is the Square Root of 16/3?

The square root is the inverse of the square of a number. 16/3 is not a perfect square. The square root of 16/3 is expressed in both radical and exponential form. In radical form, it is expressed as √(16/3), whereas (16/3)^(1/2) is the exponential form. √(16/3) = 2.3094, which is an irrational number because it cannot be expressed as a fraction p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 16/3

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

  • Long division method
  • Approximation method

Square Root of 16/3 by Long Division Method

The long division method is particularly used for non-perfect square numbers. Here is how to find the square root of 16/3 using the long division method:

Step 1: Convert the fraction 16/3 into a decimal. 16/3 = 5.3333...

Step 2: Use the long division method to find the square root of 5.3333.

Step 3: Estimate a number whose square is less than or equal to 5. Start with 2 because 2^2 = 4, which is less than 5.3333.

Step 4: Bring down the next pair of digits after the decimal point. Divide 1.3333 by 4 to get 0.3333.

Step 5: Continue the division to get more decimal places. The quotient becomes 2.3094 when rounded to four decimal places.

So, the square root of √(16/3) is approximately 2.3094.

Square Root of 16/3 by Approximation Method

The approximation method is another way to find square roots. It is a simple method to estimate the square root of a given number. Now let us learn how to find the square root of 16/3 using the approximation method.

Step 1: Estimate the value of √(5.3333) since 16/3 = 5.3333.

Step 2: Find two numbers between which 5.3333 lies. It lies between 4 (2^2) and 9 (3^2).

Step 3: Use interpolation to approximate the value. Given number = 5.3333 Smallest perfect square = 4 Largest perfect square = 9 Using the formula: (5.3333 - 4) / (9 - 4) ≈ 0.2667

Step 4: Add the decimal to the smaller root value: 2 + 0.2667 = 2.2667 So, the square root of 16/3 is approximately 2.2667.

Common Mistakes and How to Avoid Them in the Square Root of 16/3

Students often make mistakes while finding the square root, such as ignoring the negative square root or skipping methods like long division. Let's look at a few common mistakes in detail.

Problem 1

Can you help Max find the area of a square box if its side length is given as √(25/3)?

Okay, lets begin

The area of the square is approximately 27.778 square units.

Explanation

The area of the square = side^2.

The side length is given as √(25/3).

Area of the square = (√(25/3))^2 = 25/3 ≈ 8.333

Therefore, the area of the square box is approximately 27.778 square units.

Problem 2

A square-shaped garden measures 16/3 square meters. If each of the sides is √(16/3), what will be the square meters of half of the garden?

Okay, lets begin

8/3 square meters.

Explanation

We divide the given area by 2 since the garden is square-shaped.

Dividing 16/3 by 2 gives us 8/3.

So, half of the garden measures 8/3 square meters.

Problem 3

Calculate √(16/3) × 6.

Okay, lets begin

Approximately 13.8564.

Explanation

First, find the square root of 16/3, which is approximately 2.3094.

Then multiply 2.3094 by 6.

So, 2.3094 × 6 ≈ 13.8564.

Problem 4

What will be the square root of (16/3 + 2/3)?

Okay, lets begin

The square root is approximately 2.

Explanation

First, find the sum of (16/3 + 2/3). 16/3 + 2/3 = 18/3 = 6.

Then, find the square root of 6, which is approximately 2.4495.

Therefore, the square root of (16/3 + 2/3) is approximately ±2.4495.

Problem 5

Find the perimeter of a rectangle if its length ‘l’ is √(16/3) units and the width ‘w’ is 5 units.

Okay, lets begin

The perimeter of the rectangle is approximately 14.6188 units.

Explanation

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

Perimeter = 2 × (√(16/3) + 5)

Perimeter = 2 × (2.3094 + 5) ≈ 14.6188 units.
