Square Root of 1125
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 1125.
What is the Square Root of 1125?
The square root is the inverse of the square of the number. 1125 is not a perfect square. The square root of 1125 is expressed in both radical and exponential form. In the radical form, it is expressed as √1125, whereas (1125)^(1/2) in the exponential form. √1125 ≈ 33.541, 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.
Finding the Square Root of 1125
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:
- Prime factorization method
- Long division method
- Approximation method
Square Root of 1125 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 1125 is broken down into its prime factors.
Step 1: Finding the prime factors of 1125 Breaking it down, we get 3 x 3 x 5 x 5 x 5: 3^2 x 5^3
Step 2: Now we found out the prime factors of 1125. The second step is to make pairs of those prime factors. Since 1125 is not a perfect square, therefore the digits of the number can’t be grouped in perfect pairs. Therefore, calculating 1125 using prime factorization requires taking one factor from each pair and multiplying them together, √1125 = 3 x 5√5 = 15√5.
Square Root of 1125 by Long Division Method
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 1125, we need to group it as 11 and 25.
Step 2: Now we need to find n whose square is less than or equal to 11. We can say n is '3' because 3 x 3 = 9, which is less than 11. Now the quotient is 3, and after subtracting 11 - 9, the remainder is 2.
Step 3: Now let us bring down 25, which is the new dividend. Add the old divisor with the same number, 3 + 3, we get 6, which will be our new divisor.
Step 4: The new divisor will be 60 + n, where n is the new digit in the quotient. We need to find the value of n.
Step 5: The next step is finding 60n x n ≤ 225. Let us consider n as 3, now 60 x 3 + 3 x 3 = 189.
Step 6: Subtract 225 from 189, the difference is 36, and the quotient is 33.
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 3600.
Step 8: Now we need to find the new divisor that is 669 because 669 x 5 = 3345.
Step 9: Subtracting 3345 from 3600, we get the result 255.
Step 10: Now the quotient is 33.5.
Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there is no decimal value, continue till the remainder is zero. So the square root of √1125 is approximately 33.54.
Square Root of 1125 by Approximation Method
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 1125 using the approximation method.
Step 1: Now we have to find the closest perfect square of √1125. The smallest perfect square less than 1125 is 1024, and the largest perfect square greater than 1125 is 1156. √1125 falls somewhere between 32 and 34.
Step 2: Now we need to apply the formula: (Given number - smallest perfect square) ÷ (Greater perfect square - smallest perfect square). Going by the formula (1125 - 1024) ÷ (1156 - 1024) = 0.7656. Using the formula, we identified the decimal point of our square root approximation. The next step is adding the value we got initially to the decimal number, which is 32 + 0.7656 ≈ 32.77, so the square root of 1125 is approximately 33.54 when using a more precise calculation.
Common Mistakes and How to Avoid Them in the Square Root of 1125
Students do make mistakes while finding the square root, like forgetting about the negative square root or skipping steps in long division methods. Now let us look at a few of those mistakes that students tend to make in detail.
Mistake 1
Forgetting about the negative square root
It is important to make students aware that a number does have both positive and negative square roots. However, we will be taking only the positive square root, as it is the required one.
For example: √50 = 7.07, there is also -7.07 which should not be forgotten.
Mistake 2
Not adding the square root symbol in proper places
Not using the square root properly is another mistake that children make. To resolve this, we need to teach children that simplifying the numbers inside the square root is important and then move on to the second step.
For example: √(12 + 24) = √12 + √24 is a wrong method of using roots. The right way of using roots is √(12 + 24) = √36.
Mistake 3
Not finding the correct value of a non-perfect square
The first step that needs to be taught to children is to simplify the numbers inside the square root. This is important so that students do not make mistakes while identifying the approximate value.
For example: √50 = 7 is wrong, the correct answer is √50 = 7.071067.
Mistake 4
Confusing the square root symbol with the cube root
Students need to be taught the difference between cube root and square root constantly as this will help them keep away from mistakes.
For example: √50 and ∛50 are different.
Mistake 5
Making mistakes in long division
Finding a square root using the long division method involves many steps. Due to this, many students might skip a step accidentally, which results in a wrong answer at the end of the sum. This may either happen in subtracting or elsewhere.
Square Root of 1125 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √1125?
The area of the square is 1125 square units.
Explanation
The area of the square = side^2.
The side length is given as √1125.
Area of the square = side^2 = √1125 x √1125 = 1125.
Therefore, the area of the square box is 1125 square units.
Problem 2
A square-shaped building measuring 1125 square feet is built; if each of the sides is √1125, what will be the square feet of half of the building?
562.5 square feet
Explanation
We can just divide the given area by 2 as the building is square-shaped.
Dividing 1125 by 2 gives us 562.5.
So half of the building measures 562.5 square feet.
Problem 3
Calculate √1125 x 5.
167.705
Explanation
The first step is to find the square root of 1125, which is approximately 33.541.
The second step is to multiply 33.541 by 5.
So 33.541 x 5 ≈ 167.705.
Problem 4
What will be the square root of (1125 + 25)?
The square root is 35.
Explanation
To find the square root, we need to find the sum of (1125 + 25). 1125 + 25 = 1150, and then √1150 ≈ 33.91.
Therefore, the approximate square root of (1125 + 25) is ±33.91, but for simplicity, it's considered as 34 for whole number approximation.
Problem 5
Find the perimeter of the rectangle if its length ‘l’ is √1125 units and the width ‘w’ is 38 units.
We find the perimeter of the rectangle as approximately 143.08 units.
Explanation
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√1125 + 38) ≈ 2 × (33.541 + 38) ≈ 2 × 71.541 ≈ 143.08 units.
