Square Root of 174240
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 and finance. Here, we will discuss the square root of 174240.
What is the Square Root of 174240?
The square root is the inverse of the square of the number. 174240 is not a perfect square. The square root of 174240 is expressed in both radical and exponential form. In the radical form, it is expressed as √174240, whereas (174240)^(1/2) in the exponential form. √174240 ≈ 417.471, 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 174240
The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, 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 174240 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 174240 is broken down into its prime factors.
Step 1: Finding the prime factors of 174240 Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 3 x 5 x 29 x 37: 2^5 x 3 x 5 x 29 x 37
Step 2: Now we found out the prime factors of 174240. The second step is to make pairs of those prime factors. Since 174240 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating the square root of 174240 using prime factorization is not feasible.
Square Root of 174240 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 174240, we need to group it as 40, 24, and 17.
Step 2: Now we need to find n whose square is closest to 17. We can say n is '4' because 4 × 4 = 16, which is less than or equal to 17. Now the quotient is 4. After subtracting 16 from 17, the remainder is 1.
Step 3: Bring down 24, making the new dividend 124. Add the old divisor with the same number, 4 + 4, to get 8, which will be our new divisor.
Step 4: Find the largest digit n where 8n × n ≤ 124. n is 1 because 81 × 1 = 81, which is less than 124.
Step 5: Subtract 81 from 124 to get 43, and the quotient becomes 41.
Step 6: Bring down the next pair of digits, 40, making the new dividend 4340. The new divisor is 82.
Step 7: Find n where 82n × n ≤ 4340. n is 5 because 825 × 5 = 4125.
Step 8: Subtract 4125 from 4340 to get 215. The quotient becomes 415.
Step 9: Since the dividend is less than the divisor, add a decimal point. Adding the decimal point allows us to bring down two zeroes, making the dividend 21500.
Step 10: Find the new divisor, 417, because 4171 × 1 = 4171.
Step 11: Subtracting 4171 from 21500 gives a remainder, and the process continues to achieve further accuracy. The square root of 174240 is approximately 417.47.
Square Root of 174240 by Approximation Method
The approximation method is an easy method to find the square root of a given number. Now let us learn how to find the square root of 174240 using the approximation method.
Step 1: Identify the closest perfect squares to 174240. The smallest perfect square is 169000 (410^2), and the largest perfect square is 176400 (420^2). √174240 falls between 410 and 420.
Step 2: Use interpolation: (Given number - smallest perfect square) / (Largest perfect square - smallest perfect square). Applying the formula: (174240 - 169000) / (176400 - 169000) = 0.8075 Adding this to 410 gives 410 + 0.8075 = 410.81. So, the square root of 174240 is approximately 410.81.
Common Mistakes and How to Avoid Them in the Square Root of 174240
Students can make errors when finding the square root. For instance, they may forget about the negative square root or skip steps in the long division method. Now, let's look at a few of these common mistakes in detail.
Mistake 1
Forgetting about the negative square root
It is important to make students aware that a number has both positive and negative square roots. However, we usually take only the positive square root, as it is the required one.
For example: √174240 ≈ 417.471, but there is also -417.471, which should not be forgotten.
Square Root of 174240 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √174240?
The area of the square is 174240 square units.
Explanation
The area of the square = side^2.
The side length is given as √174240.
Area of the square = (√174240) × (√174240) = 174240.
Therefore, the area of the square box is 174240 square units.
Problem 2
A square-shaped building measuring 174240 square feet is built; if each of the sides is √174240, what will be the square feet of half of the building?
87120 square feet
Explanation
We can divide the given area by 2 as the building is square-shaped.
Dividing 174240 by 2 = 87120.
So half of the building measures 87120 square feet.
Problem 3
Calculate √174240 × 5.
Approx. 2087.35
Explanation
The first step is to find the square root of 174240, which is approximately 417.471.
Multiply 417.471 by 5.
So, 417.471 × 5 ≈ 2087.35.
Problem 4
What will be the square root of (174240 + 360)?
The square root is approximately 418.
Explanation
To find the square root, first find the sum of (174240 + 360).
174240 + 360 = 174600.
The square root of 174600 is approximately 418.
Therefore, the square root of 174600 is ±418.
Problem 5
Find the perimeter of the rectangle if its length ‘l’ is √174240 units and the width ‘w’ is 100 units.
The perimeter of the rectangle is approximately 1034.94 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√174240 + 100) = 2 × (417.471 + 100) = 2 × 517.471 = 1034.94 units.
