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 2048.
The square root is the inverse of the square of the number. 2048 is not a perfect square. The square root of 2048 is expressed in both radical and exponential form. In the radical form, it is expressed as √2048, whereas (2048)^(1/2) in the exponential form. √2048 ≈ 45.2548, 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 2048 is broken down into its prime factors.
Step 1: Finding the prime factors of 2048 Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2: 2^11
Step 2: Now we found out the prime factors of 2048. The second step is to make pairs of those prime factors. Since 2048 is not a perfect square, therefore the digits of the number can’t be grouped in pairs. Therefore, calculating 2048 using prime factorization is impossible for a perfect square.
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 2048, we need to group it as 48 and 20.
Step 2: Now we need to find n whose square is ≤ 20. We can say n as '4' because 4 x 4 = 16 is lesser than or equal to 20. Now the quotient is 4 after subtracting 16 from 20, the remainder is 4.
Step 3: Now let us bring down 48 which is the new dividend. Add the old divisor with the same number 4 + 4 we get 8 which will be our new divisor.
Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 8n as the new divisor, we need to find the value of n.
Step 5: The next step is finding 8n × n ≤ 448. Let us consider n as 5, now 85 x 5 = 425.
Step 6: Subtract 448 from 425, the difference is 23, and the quotient is 45.
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 2300.
Step 8: Now we need to find the new divisor that is 452 because 452 x 5 = 2260.
Step 9: Subtracting 2260 from 2300, we get the result 40.
Step 10: Now the quotient is 45.2.
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 √2048 is approximately 45.25.
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 2048 using the approximation method.
Step 1: Now we have to find the closest perfect squares of √2048. The smallest perfect square less than 2048 is 2025 and the largest perfect square greater than 2048 is 2116. √2048 falls somewhere between 45 and 46.
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 (2048 - 2025) ÷ (2116 - 2025) ≈ 0.253.
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 45 + 0.253 = 45.253, so the square root of 2048 is approximately 45.253.
Students do make mistakes while finding the square root, like 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 √1800?
The area of the square is 1800 square units.
The area of the square = side^2.
The side length is given as √1800.
Area of the square = side^2 = √1800 x √1800 = 1800.
Therefore, the area of the square box is 1800 square units.
A square-shaped building measuring 2048 square feet is built; if each of the sides is √2048, what will be the square feet of half of the building?
1024 square feet
We can just divide the given area by 2 as the building is square-shaped.
Dividing 2048 by 2 = we get 1024.
So half of the building measures 1024 square feet.
Calculate √2048 x 7.
316.7836
The first step is to find the square root of 2048, which is approximately 45.2548.
The second step is to multiply 45.2548 with 7.
So 45.2548 x 7 ≈ 316.7836.
What will be the square root of (1800 + 28)?
The square root is 44
To find the square root, we need to find the sum of (1800 + 28). 1800 + 28 = 1828, and then √1828 ≈ 42.76.
Therefore, the square root of (1800 + 28) is approximately 42.76.
Find the perimeter of the rectangle if its length 'l' is √1800 units and the width 'w' is 40 units.
We find the perimeter of the rectangle as approximately 186.88 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√1800 + 40) = 2 × (42.4264 + 40) = 2 × 82.4264 ≈ 164.85 units.
