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 like vehicle design, finance, etc. Here, we will discuss the square root of 653.
The square root is the inverse of the square of the number. 653 is not a perfect square. The square root of 653 is expressed in both radical and exponential form. In the radical form, it is expressed as √653, whereas (653)^(1/2) in the exponential form. √653 ≈ 25.549, 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, for non-perfect square numbers, the long division method and approximation method are used. Let us now learn the following methods:
The prime factorization of a number involves expressing it as a product of prime factors. However, as 653 is a non-perfect square and also a prime number, it cannot be broken down into smaller prime factors. Therefore, calculating the square root of 653 using prime factorization is not feasible.
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 653, we need to group it as 53 and 6.
Step 2: Now we need to find n whose square is less than or equal to 6. We can say n is ‘2’ because 2 × 2 = 4, which is less than 6. Subtracting, we get a remainder of 2.
Step 3: Bring down 53 to make the new dividend 253. Add the old divisor with the same number 2 + 2 = 4, which will be our new divisor.
Step 4: The new divisor is 4n. We need to find n such that 4n × n ≤ 253. Let us consider n as 5, now 45 × 5 = 225.
Step 5: Subtract 225 from 253, the difference is 28, and the quotient is 25.
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 zeros to the dividend. Now the new dividend is 2800.
Step 7: Now we need to find the new divisor which is 510 because 510 × 5 = 2550.
Step 8: Subtracting 2550 from 2800, we get the result 250.
Step 9: The quotient is 25.5. Step 10: Continue this method to find more decimal places of the square root.
So the square root of √653 is approximately 25.549.
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 653 using the approximation method.
Step 1: Find the closest perfect square of √653. The smallest perfect square less than 653 is 625 and the largest perfect square more than 653 is 676. √653 falls somewhere between 25 and 26.
Step 2: Apply the formula (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Using the formula (653 - 625) / (676 - 625) = 28 / 51 ≈ 0.549. Adding this to 25 gives us the approximate square root: 25 + 0.549 = 25.549.
Therefore, the square root of 653 is approximately 25.549.
Students often make mistakes while finding square roots, such as forgetting about the negative square root or skipping steps in the long division method. Now, let us look at a few of these mistakes in detail.
Can you help Max find the area of a square box if its side length is given as √653?
The area of the square is 653 square units.
The area of the square = side².
The side length is given as √653.
Area of the square = side² = √653 × √653 = 653.
Therefore, the area of the square box is 653 square units.
A square-shaped building measuring 653 square feet is built. If each of the sides is √653, what will be the square feet of half of the building?
326.5 square feet.
We can just divide the given area by 2 as the building is square-shaped.
Dividing 653 by 2 = 326.5.
So half of the building measures 326.5 square feet.
Calculate √653 × 5.
127.745
First, find the square root of 653, which is approximately 25.549.
Then multiply 25.549 by 5.
So, 25.549 × 5 = 127.745.
What will be the square root of (653 + 3)?
The square root is 26.
To find the square root, we need to find the sum of (653 + 3).
653 + 3 = 656, and then √656 ≈ 25.612.
Therefore, the square root of (653 + 3) is approximately ±25.612.
Find the perimeter of the rectangle if its length ‘l’ is √653 units and the width ‘w’ is 38 units.
The perimeter of the rectangle is approximately 127.098 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√653 + 38)
= 2 × (25.549 + 38)
= 2 × 63.549
= 127.098 units.
