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 fields such as vehicle design, finance, etc. Here, we will discuss the square root of 2.44.
The square root is the inverse of the square of the number. 2.44 is not a perfect square. The square root of 2.44 is expressed in both radical and exponential form. In the radical form, it is expressed as √2.44, whereas (2.44)^(1/2) in the exponential form. √2.44 = 1.562, 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.
The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers; instead, the long-division method and approximation method are used. Let us now learn the following methods:
The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.
Step 1: To begin with, we need to consider 2.44 as 244 (by multiplying by 100 for ease).
Step 2: Find a number whose square is closest to 244. The number is 1, as 1 × 1 = 1 is less than 2.
Step 3: Subtract 1 from 2 to get the remainder 1, and bring down 44 to make it 144.
Step 4: Double the divisor (1) to get 2, and find a digit n such that 2n × n is less than or equal to 144. Here, n = 6 works since 26 × 6 = 156, which fits.
Step 5: Subtract 156 from 144 to get the remainder -12.
Step 6: Since the remainder is less than the divisor, add a decimal point and bring down two zeroes to make it 1200.
Step 7: Repeat the process to get a more precise square root value. So, the square root of √2.44 is approximately 1.562.
The approximation method is another method for finding square roots; it is an easy method to estimate the square root of a given number. Let us learn how to find the square root of 2.44 using the approximation method.
Step 1: Find the closest perfect squares around 2.44. The closest smaller perfect square is 1 (√1 = 1), and the closest larger perfect square is 4 (√4 = 2). √2.44 falls between 1 and 2.
Step 2: Apply the formula for approximation: (Given number - smaller perfect square) / (Larger perfect square - smaller perfect square). (2.44 - 1) / (4 - 1) = 1.44 / 3 = 0.48 Using the formula, we identified the decimal point of our square root. Adding it to the lower bound: 1 + 0.48 = 1.48. Further refinement gives us approximately 1.562.
Students often make mistakes while finding the square root, such as forgetting about the negative square root or skipping steps in the long division method. Let's look at a few of these mistakes in detail.
Can you help Max find the area of a square box if its side length is given as √24.4?
The area of the square is approximately 24.4 square units.
The area of the square = side².
The side length is given as √24.4.
Area = (√24.4)² = 24.4.
Therefore, the area of the square box is approximately 24.4 square units.
A square-shaped building measuring 2.44 square meters is built; if each side is √2.44, what will be the area of half of the building?
1.22 square meters
We can divide the given area by 2 as the building is square-shaped.
Dividing 2.44 by 2 gives us 1.22.
So half of the building measures 1.22 square meters.
Calculate √2.44 × 5.
Approximately 7.81
The first step is to find the square root of 2.44, which is approximately 1.562.
The second step is to multiply 1.562 by 5.
So, 1.562 × 5 ≈ 7.81.
What will be the square root of (2.44 + 0.56)?
The square root is approximately 1.732.
To find the square root, we sum (2.44 + 0.56) to get 3.
Then √3 ≈ 1.732.
Therefore, the square root of (2.44 + 0.56) is approximately ±1.732.
Find the perimeter of the rectangle if its length 'l' is √2.44 units and the width 'w' is 3 units.
We find the perimeter of the rectangle is approximately 9.124 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√2.44 + 3)
= 2 × (1.562 + 3)
= 2 × 4.562
= 9.124 units.
