Square Root of 3/4
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 like vehicle design, finance, etc. Here, we will discuss the square root of 3/4.
What is the Square Root of 3/4?
The square root is the inverse of the square of a number. 3/4 is not a perfect square. The square root of 3/4 is expressed in both radical and exponential form. In radical form, it is expressed as √(3/4), whereas (3/4)^(1/2) in exponential form. √(3/4) = √3/2, 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 3/4
Since 3/4 is a fraction, we use the property of square roots that allows us to take the square root of the numerator and the denominator separately. Let us now learn the following methods:
- Prime factorization method
- Simplification method
- Numerical approximation method
Square Root of 3/4 by Simplification Method
The simplification method allows us to find the square root of a fraction by taking the square root of the numerator and the denominator separately. Step 1: The numerator is 3, and the denominator is 4. Step 2: Take the square root of each part separately: √3 and √4. Step 3: The square root of 4 is 2, as 2 x 2 = 4. Step 4: Therefore, the square root of 3/4 is √3/2.
Square Root of 3/4 by Numerical Approximation
Numerical approximation is a method used to find a more precise decimal value for the square root of a number.
Step 1: Approximate the square root of the numerator, √3 ≈ 1.732.
Step 2: The square root of the denominator, √4, is 2.
Step 3: Divide the approximate square root of the numerator by the exact square root of the denominator: 1.732/2 = 0.866.
Square Root of 3/4 by Prime Factorization Method
The prime factorization method is generally used for whole numbers, but it can help us understand the properties of the square roots involved.
Step 1: Prime factorization of 3 is itself, as it's a prime number.
Step 2: Prime factorization of 4 is 2 x 2.
Step 3: As we cannot form complete pairs for 3, it indicates the result will be irrational.
Comparison with Whole Number Square Roots
It is useful to compare the value of √(3/4) with the square roots of whole numbers to understand its relative size.
Step 1: We know √1 = 1, which is greater than 0.866.
Step 2: Therefore, √(3/4) ≈ 0.866 is less than 1 but greater than √0.
Common Mistakes and How to Avoid Them in the Square Root of 3/4
Students often make mistakes while finding the square root of fractions, such as not simplifying the fraction beforehand or confusing numerator and denominator. Now let us look at a few of those mistakes in detail.
Mistake 1
Not Simplifying the Fraction First
It's important to simplify the fraction before taking the square root.
For example, if a fraction like 6/8 is given, simplify it to 3/4 before proceeding with finding its square root.
Square Root of 3/4 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √(3/4)?
The area of the square is 0.75 square units.
Explanation
The area of the square = side^2.
The side length is given as √(3/4).
Area of the square = (√(3/4))^2 = 3/4 = 0.75.
Therefore, the area of the square box is 0.75 square units.
Problem 2
A square-shaped garden measures 3/4 square feet; if each of the sides is √(3/4), what will be the square feet of half of the garden?
0.375 square feet
Explanation
We can just divide the given area by 2 as the garden is square-shaped.
Dividing 3/4 by 2 = we get 3/8 = 0.375.
So half of the garden measures 0.375 square feet.
Problem 3
Calculate √(3/4) x 8.
6.928
Explanation
The first step is to find the square root of 3/4, which is approximately 0.866.
The second step is to multiply 0.866 by 8.
So 0.866 x 8 = 6.928.
Problem 4
What will be the square root of (3/4 + 1/4)?
The square root is 1.
Explanation
To find the square root, we need to find the sum of (3/4 + 1/4) 3/4 + 1/4 = 1, and then √1 = 1.
Therefore, the square root of (3/4 + 1/4) is 1.
Problem 5
Find the perimeter of a rectangle if its length ‘l’ is √(3/4) units and the width ‘w’ is 1 unit.
The perimeter of the rectangle is 3.732 units.
Explanation
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√(3/4) + 1) = 2 × (0.866 + 1) = 2 × 1.866 = 3.732 units.
