Square Root of 1226
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 various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 1226.
What is the Square Root of 1226?
The square root is the inverse of the square of the number. 1226 is not a perfect square. The square root of 1226 is expressed in both radical and exponential form. In the radical form, it is expressed as √1226, whereas (1226)^(1/2) in the exponential form. √1226 ≈ 35.01428, 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 1226
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 1226 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 1226 is broken down into its prime factors.
Step 1: Finding the prime factors of 1226 Breaking it down, we get 2 × 613
Step 2: Now we found out the prime factors of 1226. Since 1226 is not a perfect square, calculating √1226 using prime factorization directly is not feasible.
Square Root of 1226 by Long Division Method
The long division method is particularly used for non-perfect square numbers. 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 1226, we need to group it as 26 and 12.
Step 2: Find n whose square is less than or equal to 12. We can say n as 3 because 3 × 3 = 9 is less than 12. Now the quotient is 3 after subtracting 9 from 12, the remainder is 3.
Step 3: Bring down 26, making it the new dividend, 326. Add the old divisor with the same number 3 + 3 = 6, which will be our new divisor.
Step 4: The new divisor will be 6n (where n is part of the quotient). We find n such that 6n × n ≤ 326. Step 5: Let n = 5, then 65 × 5 = 325.
Step 6: Subtract 325 from 326, the difference is 1, and the quotient is 35.
Step 7: Since the dividend is smaller 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 100.
Step 8: Calculate the new divisor, 700, by adding a decimal number to the quotient and repeating the steps to get more decimal places.
So the square root of √1226 is approximately 35.01.
Square Root of 1226 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 1226 using the approximation method.
Step 1: Find the closest perfect squares to √1226. The smallest perfect square less than 1226 is 1225, and the largest perfect square greater than 1226 is 1296. √1226 falls between 35 and 36.
Step 2: Apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) Using the formula: (1226 - 1225) / (1296 - 1225) ≈ 0.014 Adding this decimal to the smaller perfect square root gives 35 + 0.014 = 35.014, so the square root of 1226 is approximately 35.014.
Common Mistakes and How to Avoid Them in the Square Root of 1226
Students often make mistakes while finding square roots, such as ignoring the negative square root or skipping steps in the long division method. Let us examine a few common mistakes in detail.
Mistake 1
Forgetting about the negative square root
It is important to remind students that a number has both positive and negative square roots. However, we typically use the positive square root, as it is the most applicable in many real-world scenarios.
For example, √50 = 7.07, there is also -7.07.
Mistake 2
Not adding the square root symbol in proper places
Incorrect use of the square root symbol is another common error. To avoid this, students should simplify the expression inside the square root before proceeding.
For example, √(12 + 24) = √36 is correct, while √12 + √24 is incorrect.
Mistake 3
Not finding the correct value of a non-perfect square
Students should simplify numbers inside the square root to avoid errors in approximating values.
For example, √50 ≈ 7.071, not 7.
Mistake 4
Confusing the square root symbol with the cube root
Students need to distinguish between cube root and square root symbols.
For example, √50 and ∛50 are different.
Mistake 5
Making mistakes in long division
The long division method involves many steps, and students may skip steps accidentally, resulting in incorrect answers. This can occur during subtraction or other steps.
Square Root of 1226 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √1226?
The area of the square is approximately 1226 square units.
Explanation
The area of the square = side^2.
The side length is given as √1226.
Area of the square = (√1226)² = 1226.
Therefore, the area of the square box is approximately 1226 square units.
Problem 2
A square-shaped building measuring 1226 square feet is built; if each of the sides is √1226, what will be the square feet of half of the building?
613 square feet
Explanation
Since the building is square-shaped, dividing the total area by 2 gives the area of half the building.
Dividing 1226 by 2 = 613
So half of the building measures 613 square feet.
Problem 3
Calculate √1226 × 3.
105.04284
Explanation
First, find the square root of 1226 which is approximately 35.014.
Then, multiply this by 3.
35.014 × 3 ≈ 105.04284
Problem 4
What will be the square root of (1225 + 1)?
The square root is approximately 35.014
Explanation
To find the square root, calculate the sum (1225 + 1) = 1226, then find √1226 ≈ 35.014.
Problem 5
Find the perimeter of a rectangle if its length ‘l’ is √1226 units and the width ‘w’ is 40 units.
The perimeter of the rectangle is approximately 150.02856 units.
Explanation
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√1226 + 40)
≈ 2 × (35.014 + 40)
= 2 × 75.014
= 150.02856 units.
