Distributive Property Meaning In Hindi

Distributive Property Meaning in Hindi: वितरण गुणधर्म की गहन समझ

The distributive property, or vitaran gunadharma (वितरण गुणधर्म) in Hindi, is a fundamental concept in mathematics that governs how multiplication interacts with addition and subtraction. Understanding this property is crucial for simplifying algebraic expressions, solving equations, and mastering more advanced mathematical concepts. This article will explore the distributive property in detail, providing a comprehensive understanding suitable for learners of all levels. We'll cover its meaning, applications, and demonstrate its use with numerous examples.

Introduction: परिचय

The distributive property states that multiplying a number by a sum (or difference) is the same as multiplying the number by each term in the sum (or difference) and then adding (or subtracting) the products. In simpler terms, it allows us to "distribute" the multiplication across the terms within the parentheses. This seemingly simple rule has far-reaching consequences in various mathematical operations.

The Property in Mathematical Notation: गणितीय संकेतन में गुणधर्म

The distributive property can be expressed using algebraic notation as follows:

• For addition: a × (b + c) = (a × b) + (a × c)
• For subtraction: a × (b – c) = (a × b) – (a × c)

Here, 'a', 'b', and 'c' represent any numbers (integers, fractions, decimals, etc.). The property holds true regardless of whether the numbers are positive or negative.

Understanding the Concept with Examples: उदाहरणों के साथ अवधारणा को समझना

Let's break down the distributive property with some examples, illustrating its application in different contexts:

Example 1: Simple Integers

Let's say we want to calculate 5 × (2 + 3). We can solve this directly: 5 × (2 + 3) = 5 × 5 = 25.

Now, let's apply the distributive property:

5 × (2 + 3) = (5 × 2) + (5 × 3) = 10 + 15 = 25

As you can see, both methods yield the same result, demonstrating the validity of the distributive property.

Example 2: Involving Negative Numbers

Let's consider -4 × (6 - 2):

Direct calculation: -4 × (6 - 2) = -4 × 4 = -16

Using the distributive property:

-4 × (6 - 2) = (-4 × 6) – (-4 × 2) = -24 – (-8) = -24 + 8 = -16

Again, the result is identical. This shows that the distributive property works seamlessly even with negative numbers.

Example 3: Fractions and Decimals

The distributive property works equally well with fractions and decimals:

0.5 × (3 + 4) = (0.5 × 3) + (0.5 × 4) = 1.5 + 2 = 3.5

(1/2) × (6 - 4) = ((1/2) × 6) – ((1/2) × 4) = 3 - 2 = 1

Example 4: Algebraic Expressions

The distributive property is exceptionally useful when working with algebraic expressions. Consider:

3x × (2x + 5)

Applying the distributive property:

3x × (2x + 5) = (3x × 2x) + (3x × 5) = 6x² + 15x

This demonstrates how the distributive property simplifies complex algebraic expressions, enabling further manipulation and solving of equations.

Example 5: Real-world Applications: वास्तविक दुनिया में अनुप्रयोग

The distributive property isn't just a theoretical concept; it has practical applications in various real-world scenarios. Consider calculating the total cost of multiple items:

Suppose you buy 3 items, each costing ₹25, and 2 items, each costing ₹15. You could calculate the total cost as:

3 × ₹25 + 2 × ₹15 = ₹75 + ₹30 = ₹105

Or, using the distributive property, we can represent this as:

(3 + 2) × ₹25 – (3+2) × (₹25-₹10) = 5 × ₹25 - 5 × ₹15 = ₹125 - ₹75 = ₹50

While this example might seem simpler without the distributive property, this underlying principle becomes significantly more efficient when dealing with many more variables or more complex scenarios.

Expanding Expressions Using the Distributive Property: वितरण गुणधर्म का उपयोग करके व्यंजकों का विस्तार

The distributive property is frequently used to expand algebraic expressions. This involves removing parentheses by applying the distributive principle. For example:

• 2(x + 3) = 2x + 6
• -5(2y - 4) = -10y + 20
• (x + 2)(x + 3) = x(x + 3) + 2(x + 3) = x² + 3x + 2x + 6 = x² + 5x + 6 (This illustrates the use of distributive property multiple times)

Factoring Expressions Using the Distributive Property: वितरण गुणधर्म का उपयोग करके व्यंजकों का गुणनखंडन

The reverse process of expanding is factoring. Here, we identify a common factor in an expression and use the distributive property to rewrite it in a more concise form. For instance:

• 4x + 8 = 4(x + 2) (Here, 4 is the common factor)
• 6x² - 9x = 3x(2x - 3) (Here, 3x is the common factor)

The Distributive Property and Combining Like Terms: समान पदों के संयोजन और वितरण गुणधर्म

Often, after applying the distributive property, you'll have an expression with like terms. These are terms that contain the same variables raised to the same powers. Combining like terms simplifies the expression further. For example:

2(x + 3) + 3x = 2x + 6 + 3x = 5x + 6

Advanced Applications: उन्नत अनुप्रयोग

The distributive property extends beyond simple algebraic manipulations. It plays a crucial role in:

• Solving equations: The distributive property is used to simplify equations before solving for the unknown variable.
• Matrix algebra: The distributive property applies to matrix multiplication, albeit with slightly different notation.
• Calculus: The distributive property is a foundation for understanding derivatives and integrals.

Frequently Asked Questions (FAQs): अक्सर पूछे जाने वाले प्रश्न

• Q: Does the distributive property work with division? A: Not directly. While you can express division as multiplication by a reciprocal (e.g., a ÷ b = a × (1/b)), you can then apply the distributive property to the resulting multiplication.

• Q: Is the distributive property only applicable to two terms within the parentheses? A: No, the distributive property can be extended to expressions with any number of terms within the parentheses. For example, a × (b + c + d) = (a × b) + (a × c) + (a × d).

• Q: What if I have multiple sets of parentheses? A: You can apply the distributive property multiple times, working from the innermost parentheses outwards.

• Q: Why is the distributive property so important? A: It is a fundamental tool for simplifying algebraic expressions, solving equations, and building a strong foundation for more advanced mathematical concepts. It provides a structured way to manipulate mathematical expressions efficiently.
