Square Root of 326
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 including engineering and finance. Here, we will discuss the square root of 326.
What is the Square Root of 326?
The square root is the inverse operation of squaring a number. Since 326 is not a perfect square, its square root is an irrational number. The square root of 326 can be expressed in both radical and exponential forms: as √326 in radical form, and as (326)^(1/2) in exponential form. The approximate value of √326 is 18.0555, which is irrational because it cannot be expressed as a ratio of two integers.
Finding the Square Root of 326
For non-perfect square numbers like 326, the prime factorization method is not suitable. Instead, methods like the long division method and approximation method are used. Let us explore these methods:
- Long division method
- Approximation method
Square Root of 326 by Long Division Method
The long division method is a systematic way of finding the square root of non-perfect square numbers. Here is how it can be applied to find √326:
Step 1: Start by grouping the digits of 326, which can be done as 3 and 26.
Step 2: Find the largest integer 'n' such that n² is less than or equal to 3. Here, n is 1, as 1 × 1 = 1. Subtract 1 from 3, leaving a remainder of 2.
Step 3: Bring down 26 to make it 226. Double the divisor (1) to get 2.
Step 4: Find the largest digit 'x' such that 2x × x ≤ 226. Here, x is 8, since 28 × 8 = 224.
Step 5: Subtract 224 from 226 to get a remainder of 2.
Step 6: Bring down two zeros to make it 200, and repeat the process by finding the next digit in the quotient.
Step 7: Continue this process until you reach a satisfactory level of precision.
The result is approximately 18.0555.
Square Root of 326 by Approximation Method
The approximation method helps estimate the square root using nearby perfect squares:
Step 1: Identify the closest perfect squares around 326. These are 324 (18²) and 361 (19²). Since 326 is closer to 324, √326 is slightly greater than 18.
Step 2: Use interpolation to find a more precise value: Let x = 326, a = 324, b = 361. Using linear interpolation: (√x - √a) / (√b - √a) = (x - a) / (b - a). Plugging in the values: (√326 - 18) / (19 - 18) = (326 - 324) / (361 - 324). This gives √326 ≈ 18 + (2/37) ≈ 18.0555.
Common Mistakes and How to Avoid Them in the Square Root of 326
Students may make errors while calculating square roots, such as neglecting negative roots, skipping steps in the long division method, or confusing square roots with cube roots. Here are some common mistakes to avoid:
Mistake 1
Forgetting about the negative square root
Remember that a number has both positive and negative square roots. Typically, the positive square root is used in practical applications, but it's important to acknowledge the existence of the negative square root.
For example, if √50 = 7.07, then -√50 = -7.07 is also valid.
Square Root of 326 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √326?
The area of the square is approximately 326 square units.
Explanation
The area of a square is given by side².
If the side length is √326, then the area is (√326)² = 326 square units.
Problem 2
A square-shaped plot of land measuring 326 square units is divided into two equal parts. What is the area of each part?
163 square units
Explanation
Since the plot is square-shaped and the total area is 326 square units, dividing it into two equal parts gives each part an area of 326 ÷ 2 = 163 square units.
Problem 3
Calculate √326 × 4.
72.222
Explanation
First, find the square root of 326, which is approximately 18.0555.
Then multiply it by 4: 18.0555 × 4 = 72.222.
Problem 4
What will be the square root of (322 + 4)?
18
Explanation
First, calculate the sum: 322 + 4 = 326.
Then find the square root: √326 ≈ 18.0555, which rounds to 18.
Problem 5
Find the perimeter of a rectangle if its length ‘l’ is √326 units and the width ‘w’ is 20 units.
The perimeter of the rectangle is approximately 76.111 units.
Explanation
Perimeter of a rectangle = 2 × (length + width).
Perimeter = 2 × (√326 + 20) ≈ 2 × (18.0555 + 20) = 2 × 38.0555 = 76.111 units.
