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 0.04.
The square root is the inverse of the square of the number. 0.04 is a perfect square. The square root of 0.04 is expressed in both radical and exponential form. In the radical form, it is expressed as √0.04, whereas (0.04)^(1/2) in the exponential form. √0.04 = 0.2, 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. For numbers that are not perfect squares, methods like the long division method and approximation method are used. Let us now learn the following methods:
The product of prime factors is the prime factorization of a number. Now let us look at how 0.04 can be broken down into its prime factors.
Step 1: Express 0.04 as a fraction, 0.04 = 4/100.
Step 2: Find the prime factors of the numerator and the denominator. 4 = 2 x 2 and 100 = 2 x 2 x 5 x 5.
Step 3: The prime factors of 0.04 are then: (2 x 2)/(2 x 2 x 5 x 5).
Step 4: Since both the numerator and denominator are perfect squares, the square root of 0.04 = √(4/100) = √4/√100 = 2/10 = 0.2.
The long division method is particularly used for non-perfect square numbers, but it can also be applied here for demonstration. Let us now learn how to find the square root using the long division method, step by step.
Step 1: To begin with, pair the digits from right to left. In the case of 0.04, we treat it as 04.
Step 2: Find a number whose square is less than or equal to 04. In this case, 2 x 2 = 4.
Step 3: The quotient is 2, and the remainder is 0.
Step 4: Since no further action is needed, the square root of 0.04 is 0.2.
The approximation method is another method for finding square roots, and it is an easy way to find the square root of a given number. Now let us learn how to find the square root of 0.04 using the approximation method.
Step 1: Identify the closest perfect squares to 0.04. The closest perfect squares are 0 and 1.
Step 2: Since 0.04 is closer to 0.01, which is 0.1 squared, and 0.04 is a perfect square of 0.2, the approximation directly gives the square root as 0.2.
Students do make mistakes while finding the square root, such as forgetting about the negative square root or skipping methods like long division. Now let us look at a few of those mistakes that students tend to make in detail.
Can you help Max find the area of a square box if its side length is given as √0.04?
The area of the square is 0.04 square units.
The area of the square = side^2.
The side length is given as √0.04.
Area of the square = side^2
= √0.04 x √0.04
= 0.2 x 0.2
= 0.04.
Therefore, the area of the square box is 0.04 square units.
A square-shaped garden measuring 0.04 square meters is built; if each of the sides is √0.04, what will be the square meters of half of the garden?
0.02 square meters
We can just divide the given area by 2 as the garden is square-shaped.
Dividing 0.04 by 2 gives us 0.02.
So half of the garden measures 0.02 square meters.
Calculate √0.04 x 5.

The first step is to find the square root of 0.04, which is 0.2.
The second step is to multiply 0.2 by 5. So 0.2 x 5 = 1.
What will be the square root of (0.01 + 0.03)?
The square root is 0.2
To find the square root, we need to find the sum of (0.01 + 0.03).
0.01 + 0.03 = 0.04, and then √0.04 = 0.2.
Therefore, the square root of (0.01 + 0.03) is ±0.2.
Find the perimeter of the rectangle if its length ‘l’ is √0.04 meters and the width ‘w’ is 0.06 meters.
We find the perimeter of the rectangle as 0.52 meters.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√0.04 + 0.06)
= 2 × (0.2 + 0.06)
= 2 × 0.26
= 0.52 meters.
