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.
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.
