This is a rational number because it can be expressed as a fraction.
Finding the Square Root of 8/9
To find the square root of a fraction, you can take the square root of the numerator and the square root of the denominator separately. Let us now learn the following methods: Simplification method Decimal approximation method
Square Root of 8/9 by Simplification Method
To simplify the square root of a fraction like 8/9, follow these steps:
Step 1: Find the square root of the numerator and the denominator separately. The numerator is 8, and the denominator is 9.
Step 2: The square root of 8 is approximately 2.82843, and the square root of 9 is exactly 3.
Step 3: Divide the square root of the numerator by the square root of the denominator: 2.82843/3 = 0.94281.
Thus, the square root of 8/9 is approximately 0.94281.
Square Root of 8/9 by Decimal Approximation Method
The decimal approximation method for finding the square root is straightforward. Here is how you can find the square root of 8/9 using this method:
Step 1: Convert the fraction 8/9 into a decimal, which is approximately 0.88889.
Step 2: Use a calculator to find the square root of 0.88889, which is approximately 0.94281.
Common Mistakes and How to Avoid Them in the Square Root of 8/9
Students often make mistakes while finding the square root, such as forgetting to simplify the fraction or incorrectly applying the square root to both the numerator and the denominator separately. Here are some common mistakes and how to avoid them.
Mistake 1
Forgetting to Simplify the Fraction
It is crucial to simplify the fraction before finding its square root when possible. For example, if the fraction can be reduced, do so before taking the square root. Simplification can lead to easier calculations and more accurate results.
Mistake 2
Not Finding the Square Root of Both Numerator and Denominator
Ensure you take the square root of both the numerator and the denominator separately.
For example, √(8/9) should be calculated as √8/√9, not simply √8/9.
Mistake 3
Incorrectly Converting to Decimal
When converting a fraction to a decimal, ensure that you divide correctly. Misplacing the decimal point or dividing incorrectly can lead to errors in the final result.
Mistake 4
Confusing Square Root with Square
Remember that a square root is not the same as squaring a number. For example, √(8/9) is not the same as (8/9)^2. Ensure you apply the correct operation.
Mistake 5
Rounding Errors in Decimal Approximation
When using the decimal approximation method, be aware of rounding errors. Ensure you round to an appropriate number of decimal places to maintain accuracy in your calculations.
Square Root of 8/9 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √(8/9)?
The area of the square is 0.88889 square units.
Explanation
The area of the square = side².
The side length is given as √(8/9).
Area of the square = (√(8/9))²
= 8/9
= 0.88889.
Therefore, the area of the square box is 0.88889 square units.
Problem 2
A square-shaped building measuring 8/9 square feet is built; if each of the sides is √(8/9), what will be the square feet of half of the building?
0.44444 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 8/9 by 2 = (8/9)/2
= 0.44444.
So half of the building measures 0.44444 square feet.
Problem 3
Calculate √(8/9) x 5.
4.71405
Explanation
The first step is to find the square root of 8/9, which is approximately 0.94281.
The second step is to multiply 0.94281 by 5. So 0.94281 x 5 = 4.71405.
Problem 4
What will be the square root of (8/9 + 1/9)?
The square root is 1.
Explanation
To find the square root, first find the sum of (8/9 + 1/9).
8/9 + 1/9 = 9/9 = 1, and then √1 = 1.
Therefore, the square root of (8/9 + 1/9) is 1.
Problem 5
Find the perimeter of the rectangle if its length 'l' is √(8/9) units and the width 'w' is 1 unit.
The perimeter of the rectangle is 3.88562 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√(8/9) + 1)
= 2 × (0.94281 + 1)
= 2 × 1.94281
= 3.88562 units.
