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 8784.
The square root is the inverse of the square of the number. 8784 is not a perfect square. The square root of 8784 is expressed in both radical and exponential form. In the radical form, it is expressed as √8784, whereas (8784)^(1/2) in the exponential form. √8784 ≈ 93.695, 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 8784 is broken down into its prime factors.
Step 1: Finding the prime factors of 8784.
Breaking it down, we get 2 × 2 × 2 × 2 × 3 × 3 × 61: 2^4 × 3^2 × 61.
Step 2: Now we found out the prime factors of 8784. The second step is to make pairs of those prime factors. Since 8784 is not a perfect square, therefore the digits of the number can’t be grouped in pairs. Therefore, calculating 8784 using prime factorization is impossible.
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 8784, we need to group it as 84 and 87.
Step 2: Now we need to find n whose square is 81. We can say n as ‘9’ because 9 × 9 is lesser than or equal to 87. Now the quotient is 9, and after subtracting 81 from 87, the remainder is 6.
Step 3: Now let us bring down 84, which is the new dividend. Add the old divisor with the same number: 9 + 9, and we get 18, which will be our new divisor.
Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 18n as the new divisor; we need to find the value of n.
Step 5: The next step is finding 18n × n ≤ 684. Let us consider n as 3, so 183 × 3 = 549.
Step 6: Subtract 549 from 684; the difference is 135, and the quotient is 93.
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 13500.
Step 8: Now we need to find the new divisor that is 936 because 936 × 6 = 5616.
Step 9: Subtracting 5616 from 13500, we get the result 7884.
Step 10: Now the quotient is 93.6.
Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose there are no decimal values; continue till the remainder is zero.
So the square root of √8784 is approximately 93.70.
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 8784 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √8784. The smallest perfect square below 8784 is 8649, and the largest perfect square above 8784 is 8836. √8784 falls somewhere between 93 and 94.
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 (8784 - 8649) ÷ (8836 - 8649) ≈ 0.695.
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 93 + 0.695 ≈ 93.695, so the square root of 8784 is approximately 93.695.
Students do make mistakes while finding the square root, such as forgetting about the negative square root or skipping long division methods. 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 √8784?
The area of the square is approximately 8784 square units.
The area of the square = side^2.
The side length is given as √8784.
Area of the square = side^2 = √8784 × √8784 = 8784.
Therefore, the area of the square box is approximately 8784 square units.
A square-shaped building measuring 8784 square feet is built; if each of the sides is √8784, what will be the square feet of half of the building?
4392 square feet.
We can just divide the given area by 2 as the building is square-shaped.
Dividing 8784 by 2 gives us 4392.
So half of the building measures 4392 square feet.
Calculate √8784 × 5.
Approximately 468.475.
The first step is to find the square root of 8784, which is approximately 93.695.
The second step is to multiply 93.695 by 5.
So 93.695 × 5 ≈ 468.475.
What will be the square root of (8784 + 16)?
The square root is approximately 94.
To find the square root, we need to find the sum of (8784 + 16). 8784 + 16 = 8800, and then √8800 ≈ 93.808, which rounds to 94.
Therefore, the square root of (8784 + 16) is approximately ±94.
Find the perimeter of the rectangle if its length ‘l’ is √8784 units and the width ‘w’ is 50 units.
We find the perimeter of the rectangle as approximately 287.39 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√8784 + 50) ≈ 2 × (93.695 + 50) ≈ 2 × 143.695 ≈ 287.39 units.
