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 various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 233.
The square root is the inverse of the square of the number. 233 is not a perfect square. The square root of 233 is expressed in both radical and exponential forms. In the radical form, it is expressed as √233, whereas (233)^(1/2) in the exponential form. √233 ≈ 15.2643, 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 the 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 233 is broken down into its prime factors.
Step 1: Finding the prime factors of 233 233 is a prime number, so it cannot be broken down into smaller prime factors.
Step 2: Since 233 is a prime number and not a perfect square, calculating the square root using prime factorization is impossible.
The long division method is particularly used for non-perfect square numbers. Let us now learn how to find the square root using the long division method, step by step.
Step 1: Group the numbers from right to left. In the case of 233, we need to group it as 33 and 2.
Step 2: Find n whose square is less than or equal to 2. We can say n is ‘1’ because 1 x 1 is less than or equal to 2. Now the quotient is 1, and after subtracting 1 from 2, the remainder is 1.
Step 3: Bring down 33, which is the new dividend. Add the old divisor (1) to itself, which gives us 2 as the new divisor.
Step 4: Use 2 as the new divisor to find a value of n such that 2n x n ≤ 133. Let us consider n as 5, now 25 x 5 = 125.
Step 5: Subtract 125 from 133, the difference is 8.
Step 6: 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 800.
Step 7: Find the new divisor, which is 105 because 1050 x 5 = 525.
Step 8: Subtracting 525 from 800 gives us the result 275.
Step 9: Continue doing these steps until we get two numbers after the decimal point. So the square root of √233 is approximately 15.26.
The approximation method is another method for finding 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 233 using the approximation method.
Step 1: Find the closest perfect square of √233. The smallest perfect square less than 233 is 225, and the largest perfect square greater than 233 is 256. √233 falls somewhere between 15 and 16.
Step 2: Apply the formula (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Using the formula (233 - 225) / (256 - 225) = 0.258. Adding the integer part to the decimal, 15 + 0.258 ≈ 15.26.
Students often make mistakes while finding the square root, such as forgetting about the negative square root or skipping the long division method. Let us look at a few common mistakes in detail.
Can you help Max find the area of a square box if its side length is given as √233?
The area of the square is 233 square units.
The area of the square = side².
The side length is given as √233.
Area of the square = side² = √233 x √233 = 233.
Therefore, the area of the square box is 233 square units.
A square-shaped building measuring 233 square feet is built; if each of the sides is √233, what will be the square feet of half of the building?
116.5 square feet
We can divide the given area by 2 as the building is square-shaped.
Dividing 233 by 2 gives us 116.5.
So half of the building measures 116.5 square feet.
Calculate √233 x 5.
76.32
The first step is to find the square root of 233, which is approximately 15.26.
The second step is to multiply 15.26 by 5.
So 15.26 x 5 = 76.32.
What will be the square root of (225 + 8)?
The square root is approximately 15.26.
To find the square root, we need to find the sum of (225 + 8).
225 + 8 = 233, and then √233 ≈ 15.26.
Therefore, the square root of (225 + 8) is approximately ±15.26.
Find the perimeter of the rectangle if its length 'l' is √233 units and the width 'w' is 38 units.
We find the perimeter of the rectangle as approximately 106.52 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√233 + 38)
= 2 × (15.26 + 38)
= 2 × 53.26
= 106.52 units.
