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 232.
The square root is the inverse of the square of a number. 232 is not a perfect square. The square root of 232 is expressed in both radical and exponential form. In the radical form, it is expressed as √232, whereas (232)^(1/2) in the exponential form. √232 ≈ 15.2315, 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.
The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where 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 232 is broken down into its prime factors.
Step 1: Finding the prime factors of 232. Breaking it down, we get 2 × 2 × 2 × 29: 2³ × 29¹
Step 2: Now we found out the prime factors of 232. The second step is to make pairs of those prime factors. Since 232 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating 232 using prime factorization is not straightforward.
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 232, we need to group it as 32 and 2.
Step 2: Now we need to find n whose square is less than or equal to 2. We can say n as ‘1’ because 1 × 1 is less than or equal to 2. Now the quotient is 1, after subtracting 2 - 1 the remainder is 1.
Step 3: Now let us bring down 32 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 × n ≤ 132. Let us consider n as 5, now 2 × 5 × 5 = 125.
Step 6: Subtract 132 from 125, the difference is 7, and the quotient is 15.
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 700.
Step 8: Now we need to find the new divisor. Consider the new divisor as 152, because 152 × 4 = 608.
Step 9: Subtracting 608 from 700 we get the result 92.
Step 10: Now the quotient is 15.4.
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 √232 ≈ 15.23.
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 232 using the approximation method.
Step 1: Now we have to find the closest perfect square of √232. The smallest perfect square less than 232 is 225 and the largest perfect square greater than 232 is 256. √232 falls somewhere between 15 and 16.
Step 2: Now we need to apply the formula that is (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula (232 - 225) ÷ (256 - 225) = 7/31 ≈ 0.226. 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 15 + 0.226 ≈ 15.23. Therefore, the square root of 232 is approximately 15.23.
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.
Can you help Max find the area of a square box if its side length is given as √232?
The area of the square is 232 square units.
The area of the square = side².
The side length is given as √232.
Area of the square = side² = √232 × √232 = 232.
Therefore, the area of the square box is 232 square units.
A square-shaped building measuring 232 square feet is built; if each of the sides is √232, what will be the square feet of half of the building?
116 square feet
We can just divide the given area by 2 as the building is square-shaped.
Dividing 232 by 2 = we get 116.
So half of the building measures 116 square feet.
Calculate √232 × 3.
45.6945
The first step is to find the square root of 232 which is approximately 15.2315, the second step is to multiply 15.2315 with 3.
So 15.2315 × 3 ≈ 45.6945.
What will be the square root of (200 + 4)?
The square root is 14.
To find the square root, we need to find the sum of (200 + 4).
200 + 4 = 204, and then 14.2829.
Therefore, the square root of (200 + 4) is approximately ±14.2829.
Find the perimeter of the rectangle if its length ‘l’ is √232 units and the width ‘w’ is 30 units.
We find the perimeter of the rectangle as 90.463 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√232 + 30)
= 2 × (15.2315 + 30)
≈ 2 × 45.2315
= 90.463 units.
