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, finance, etc. Here, we will discuss the square root of 2816.
The square root is the inverse of the square of a number. 2816 is not a perfect square. The square root of 2816 is expressed in both radical and exponential form. In radical form, it is expressed as √2816, whereas in exponential form it is (2816)^(1/2). √2816 ≈ 53.057, 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; instead, 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 2816 is broken down into its prime factors.
Step 1: Finding the prime factors of 2816 Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 2 x 11 x 11: 2^6 x 11^2
Step 2: Now that we found the prime factors of 2816, the second step is to make pairs of those prime factors. Since 2816 is not a perfect square, the digits of the number can’t be grouped into pairs.
Thus, calculating 2816 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: Begin by grouping the numbers from right to left. In the case of 2816, we need to group it as 28 and 16.
Step 2: Find n whose square is less than or equal to 28. Here, n = 5 because 5 x 5 = 25. Now the quotient is 5, and after subtracting 25 from 28, the remainder is 3.
Step 3: Bring down 16, making the new dividend 316. Add the old divisor (5) with itself, giving us 10, which will be our new divisor.
Step 4: The new divisor will be 10n. We need to find n such that 10n x n ≤ 316. Let n = 3, then 103 x 3 = 309.
Step 5: Subtract 309 from 316, resulting in a remainder of 7.
Step 6: Since the dividend is less than the divisor, add a decimal point to the quotient and bring down two zeros to the remainder, making it 700.
Step 7: The new divisor will be 106. Find n such that 106n x n ≤ 700. Let n = 6, then 1066 x 6 = 636.
Step 8: Subtract 636 from 700, resulting in a remainder of 64.
Step 9: Continue doing these steps until you get two numbers after the decimal point or until the remainder is zero.
So the square root of √2816 ≈ 53.06
The approximation method is another method for finding square roots; it is an easy method to find the square root of a given number. Let us learn how to find the square root of 2816 using the approximation method.
Step 1: Find the closest perfect square of √2816. The closest perfect squares of 2816 are 2809 and 2916. √2816 falls somewhere between 53 and 54.
Step 2: Apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Using the formula: (2816 - 2809) / (2916 - 2809) = 7 / 107 ≈ 0.065
Step 3: Add the value obtained to the lower perfect square root: 53 + 0.065 = 53.065
So the square root of 2816 ≈ 53.065
Students often make mistakes while finding the square root, such as forgetting about the negative square root or skipping steps in long division methods. 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 √2816?
The area of the square is 2816 square units.
The area of the square = side^2.
The side length is given as √2816.
Area of the square = side^2
= √2816 x √2816
= 2816.
Therefore, the area of the square box is 2816 square units.
A square-shaped building measuring 2816 square feet is built; if each of the sides is √2816, what will be the square feet of half of the building?
1408 square feet
We can divide the given area by 2 since the building is square-shaped.
Dividing 2816 by 2, we get 1408.
So half of the building measures 1408 square feet.
Calculate √2816 x 5.
265.285
The first step is to find the square root of 2816, which is approximately 53.057.
The second step is to multiply 53.057 by 5.
So 53.057 x 5 ≈ 265.285.
What will be the square root of (2816 - 16)?
The square root is 53.
To find the square root, we need to find the difference: 2816 - 16 = 2800.
2800 is close to 2809, which is a perfect square (53^2 = 2809).
Therefore, the approximate square root of 2800 is 53.
Find the perimeter of a rectangle if its length 'l' is √2816 units and the width 'w' is 50 units.
We find the perimeter of the rectangle as approximately 206.114 units.
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√2816 + 50)
≈ 2 × (53.057 + 50)
≈ 2 × 103.057
≈ 206.114 units.
