Square Root of 1/49
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 the field of vehicle design, finance, etc. Here, we will discuss the square root of 1/49.
What is the Square Root of 1/49?
The square root is the inverse of the square of the number. 1/49 is a perfect square. The square root of 1/49 is expressed in both radical and exponential form. In the radical form, it is expressed as √(1/49), whereas (1/49)^(1/2) in the exponential form. √(1/49) = 1/7, 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.
Finding the Square Root of 1/49
Since 1/49 is a perfect square, the prime factorization method is straightforward here. However, it can also be verified using the long division method or the approximation method. Let us explore these methods:
- Prime factorization method
- Long division method
- Approximation method
Square Root of 1/49 by Prime Factorization Method
The prime factorization of a number is the product of its prime factors. Now let us look at how 1/49 is broken down into its prime factors.
Step 1: Finding the prime factors of 49 49 = 7 x 7: 7²
Step 2: Since 1 is a perfect square, its square root is 1. Thus, √(1/49) = 1/7.
Square Root of 1/49 by Long Division Method
The long division method can be used to find the square root of perfect squares as well. Let us now learn how to find the square root using the long division method, step by step:
Step 1: Consider the number 1/49 as 0.0204.
Step 2: Pair the digits from right to left, starting with the decimal point: 02 and 04.
Step 3: The square root of 1 is 1, so our first divisor is 1.
Step 4: Bring down 04, making the new dividend 04.
Step 5: Double the divisor (1), resulting in 2.
Step 6: Find n such that 2n x n ≤ 4. Here, n is 0 because 20 x 0 = 0, and the remainder is 4.
Step 7: Continue with the process for further decimal places, but since this is a perfect square, we find that √(1/49) = 0.142857... which simplifies to 1/7.
Square Root of 1/49 by Approximation Method
The approximation method involves identifying the perfect squares close to our number and estimating based on those.
Step 1: Identify the perfect squares around 1/49, which are 0 and 1.
Step 2: The square root of 0 is 0, and the square root of 1 is 1, so √(1/49) falls between these values.
Step 3: Since 1/49 is exactly 1/7, the approximation method confirms the exact value: √(1/49) = 1/7.
Common Mistakes and How to Avoid Them in the Square Root of 1/49
Students often make mistakes while finding square roots, such as forgetting about the negative square root or skipping calculation steps. Let's discuss some common mistakes in detail.
Mistake 1
Forgetting about the negative square root
It is important to remember that a number has both positive and negative square roots. However, we generally take the positive square root unless specified otherwise.
For example, √(1/49) = ±1/7, but we are usually interested in the positive root.
Mistake 2
Not adding square root symbol in proper places
Using the square root symbol correctly is crucial.
For example, √(4 + 9) = √13 is not the same as √4 + √9 = 5.
Mistake 3
Not finding the correct value of a non-perfect square
Ensure to simplify numbers accurately inside the square root.
For instance, √(1/50) should be approximated correctly, unlike √(1/49).
Mistake 4
Confusing the square root symbol with the cube root
Distinguish between square root and cube root symbols.
For example, √64 is different from ∛64.
Mistake 5
Making mistakes in long division
Long division involves several steps, and missing any can lead to incorrect results. Practice is key to mastering this method.
Square Root of 1/49 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √(1/64)?
The area of the square is 1/64 square units.
Explanation
The area of the square = side².
The side length is given as √(1/64).
Area of the square = side² = √(1/64) x √(1/64) = 1/8 x 1/8 = 1/64.
Therefore, the area of the square box is 1/64 square units.
Problem 2
A square-shaped garden measuring 1/49 square units is built; if each of the sides is √(1/49), what will be the square units of half of the garden?
1/98 square units
Explanation
We can divide the given area by 2 as the garden is square-shaped.
Dividing (1/49) by 2 = 1/98.
So half of the garden measures 1/98 square units.
Problem 3
Calculate √(1/49) x 5.
5/7
Explanation
The first step is to find the square root of 1/49, which is 1/7.
The second step is to multiply 1/7 with 5.
So 1/7 x 5 = 5/7.
Problem 4
What will be the square root of (1/64 + 1/64)?
The square root is 1/8.
Explanation
To find the square root, we need to find the sum of (1/64 + 1/64). 1/64 + 1/64 = 1/32, and then √(1/32) = 1/√32 = 1/8.
Therefore, the square root of (1/64 + 1/64) is 1/8.
Problem 5
Find the perimeter of the rectangle if its length 'l' is √(1/49) units and the width 'w' is 1 unit.
We find the perimeter of the rectangle as 2.2857 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√(1/49) + 1) = 2 × (1/7 + 1) = 2 × (1.142857) = 2.2857 units.
