Square Root of 292
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 292.
What is the Square Root of 292?
The square root is the inverse of the square of the number. 292 is not a perfect square. The square root of 292 is expressed in both radical and exponential form. In the radical form, it is expressed as √292, whereas (292)^(1/2) in the exponential form. √292 ≈ 17.088, 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 292
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 292 by Prime Factorization Method
The product of prime factors is the Prime factorization of a number. Now let us look at how 292 is broken down into its prime factors.
Step 1: Finding the prime factors of 292
Breaking it down, we get 2 x 2 x 73: 2^2 x 73^1
Step 2: Now we found out the prime factors of 292. The second step is to make pairs of those prime factors. Since 292 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating √292 using prime factorization is impossible.
Square Root of 292 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 292, we need to group it as 92 and 2.
Step 2: Now we need to find n whose square is 2. We can say n is ‘1’ because 1 x 1 is lesser than or equal to 2. Now the quotient is 1, and after subtracting 1 from 2, the remainder is 1.
Step 3: Now let us bring down 92, which is the new dividend. Add the old divisor with the same number 1 + 1; we get 2, which will be our new divisor.
Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 2n as the new divisor, we need to find the value of n.
Step 5: The next step is finding 2n x n ≤ 192. Let us consider n as 7, now 27 x 7 = 189.
Step 6: Subtract 192 from 189; the difference is 3, and the quotient is 17.
Step 7: Since the dividend is less than the divisor, we need to add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 300.
Step 8: Now we need to find the new divisor. Consider n as 0, because 270 x 0 = 0.
Step 9: Subtracting 0 from 300, we get the result 300.
Step 10: The quotient is 17.0.
Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there are no decimal values, continue till the remainder is zero.
So the square root of √292 ≈ 17.088
Square Root of 292 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 292 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √292. The smallest perfect square less than 292 is 289, and the largest perfect square greater than 292 is 324. √292 falls somewhere between 17 and 18.
Step 2: Now we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula, (292 - 289) / (324 - 289) ≈ 0.088. 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 17 + 0.088 ≈ 17.088, so the square root of 292 is approximately 17.088.
Common Mistakes and How to Avoid Them in the Square Root of 292
Students do make mistakes while finding the square root, like 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 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 cube root and 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 292 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √292?
The area of the square is approximately 292 square units.
Explanation
The area of the square = side^2.
The side length is given as √292.
Area of the square = side^2 = √292 x √292 ≈ 17.088 x 17.088 ≈ 292
Therefore, the area of the square box is approximately 292 square units.
Problem 2
A square-shaped building measuring 292 square feet is built; if each of the sides is √292, what will be the square feet of half of the building?
146 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 292 by 2, we get 146.
So half of the building measures 146 square feet.
Problem 3
Calculate √292 x 5.
Approximately 85.44
Explanation
The first step is to find the square root of 292, which is approximately 17.088.
The second step is to multiply 17.088 with 5. So 17.088 x 5 ≈ 85.44
Problem 4
What will be the square root of (289 + 3)?
The square root is approximately 17.088
Explanation
To find the square root, we need to find the sum of (289 + 3). 289 + 3 = 292, and then √292 ≈ 17.088.
Therefore, the square root of (289 + 3) is approximately 17.088.
Problem 5
Find the perimeter of the rectangle if its length ‘l’ is √292 units and the width ‘w’ is 38 units.
We find the perimeter of the rectangle as approximately 110.176 units.
Explanation
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√292 + 38) ≈ 2 × (17.088 + 38) ≈ 2 × 55.088 ≈ 110.176 units.
