Square Root of 4969
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 4969.
What is the Square Root of 4969?
The square root is the inverse of the square of the number. 4969 is not a perfect square. The square root of 4969 is expressed in both radical and exponential form. In the radical form, it is expressed as √4969, whereas (4969)^(1/2) in the exponential form. √4969 ≈ 70.477, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.
Finding the Square Root of 4969
The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where the long-division method and approximation method are used. Let us now learn the following methods:
- Prime factorization method
- Long division method
- Approximation method
Square Root of 4969 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 4969 is broken down into its prime factors.
Step 1: Finding the prime factors of 4969
Breaking it down, we get 7 x 7 x 101: 7^2 x 101^1
Step 2: Now we found out the prime factors of 4969. The second step is to make pairs of those prime factors. Since 4969 is not a perfect square, therefore the digits of the number can’t be grouped in pair. Therefore, calculating √4969 using prime factorization is not straightforward.
Square Root of 4969 by Long Division Method
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 group the numbers from right to left. In the case of 4969, we need to group it as 69 and 49.
Step 2: Now we need to find n whose square is less than or equal to 49. We can say n as ‘7’ because 7 x 7 = 49. Now the quotient is 7 after subtracting 49 - 49, the remainder is 0.
Step 3: Now let us bring down 69, which is the new dividend. Add the old divisor with the same number 7 + 7, we get 14, which will be our new divisor.
Step 4: The new divisor will be 140n, where n is a digit such that 140n x n ≤ 6900.
Step 5: Continue doing these steps until we get two numbers after the decimal point. Suppose if there is no decimal value, continue until the remainder is zero.
So the square root of √4969 ≈ 70.48
Square Root of 4969 by Approximation Method
The approximation method is another method for finding the square roots; it is an easy method to find the square root of a given number. Now let us learn how to find the square root of 4969 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √4969. The smallest perfect square less than 4969 is 4900, and the largest perfect square greater than 4969 is 5041. √4969 falls somewhere between 70 and 71.
Step 2: Now we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) (4969 - 4900) / (5041 - 4900) = 69 / 141 ≈ 0.49 Using the formula, we identified the decimal point of our square root. The next step is adding the value we got initially to the decimal number, which is 70 + 0.49 ≈ 70.49.
Common Mistakes and How to Avoid Them in the Square Root of 4969
Students do make mistakes while finding the square root, likewise forgetting about the negative square root, skipping long division methods, etc. Now let us look at a few of those mistakes that students tend to make in detail.
Mistake 1
Forgetting about the negative square root
It is important to make students aware that a number does have both positive and negative square roots. However, we will be taking only the positive square root, as it is the required one.
For example: √50 = 7.07; there is also -7.07, which should not be forgotten.
Mistake 2
Not adding the square root symbol in proper places
Not using the square root properly is another mistake that children make. To resolve this, we need to teach children that simplifying the numbers inside the square root is important and then move on to the second step.
For example: √(12+24) = √12 + √24 is the wrong method of using roots.
The right way of using roots is √(12+24) = √36.
Mistake 3
Not finding the correct value of a non-perfect square
The first step that needs to be taught to children is to simplify the numbers inside the square root. This is important so that students do not make mistakes while identifying the approximate value.
For example: √50 = 7 is wrong; the correct answer is √50 ≈ 7.071.
Mistake 4
Confusing the square root symbol with the cube root
Students need to be taught the difference between the cube root and the square root constantly, as this will help them keep away from mistakes.
For example: √50 and ∛50 are different.
Mistake 5
Making mistakes in long division
Finding a square root using the long division method involves many steps. Due to this, many students might skip a step accidentally, which results in a wrong answer at the end of the sum. This may either happen in subtracting or elsewhere.
Square Root of 4969 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √4969?
The area of the square is approximately 24,696.4 square units.
Explanation
The area of the square = side^2.
The side length is given as √4969.
Area of the square = side^2 = √4969 x √4969 = 70.48 × 70.48 ≈ 24,696.4.
Therefore, the area of the square box is approximately 24,696.4 square units.
Problem 2
A square-shaped building measuring 4969 square feet is built; if each of the sides is √4969, what will be the square feet of half of the building?
2,484.5 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 4969 by 2, we get 2,484.5.
So half of the building measures 2,484.5 square feet.
Problem 3
Calculate √4969 x 5.
352.4
Explanation
The first step is to find the square root of 4969, which is approximately 70.48.
The second step is to multiply 70.48 by 5.
So 70.48 x 5 ≈ 352.4.
Problem 4
What will be the square root of (4969 + 32)?
The square root is approximately 71.
Explanation
To find the square root, we need to find the sum of (4969 + 32). 4969 + 32 = 5001, and then √5001 ≈ 70.71.
Therefore, the square root of (4969 + 32) is approximately ±70.71.
Problem 5
Find the perimeter of a rectangle if its length ‘l’ is √4969 units and the width ‘w’ is 50 units.
The perimeter of the rectangle is approximately 241 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√4969 + 50) ≈ 2 × (70.48 + 50) ≈ 2 × 120.48 ≈ 240.96.
