Introduction

In the world of mathematics, particularly in algebra, there are several properties that govern the way we perform operations on numbers and variables. These properties are essential in helping us simplify expressions, solve equations, and understand the relationships between different mathematical concepts. In this article, we will delve into one of these properties, which is illustrated by the given equation: $2\left(-\frac{3}{9}\right) = \left(-\frac{3}{9}\right)^2$ . Our goal is to identify the property that this equation represents and explore its significance in algebra.

The Equation: A Closer Look

The given equation is $2\left(-\frac{3}{9}\right) = \left(-\frac{3}{9}\right)^2$ . At first glance, this equation may seem simple, but it actually represents a fundamental property of algebra. To understand this property, let's break down the equation and analyze its components.

The left-hand side of the equation is $2\left(-\frac{3}{9}\right)$ , which involves multiplying a number by a fraction. The right-hand side of the equation is $\left(-\frac{3}{9}\right)^2$ , which involves squaring a fraction.

Simplifying the Equation

To simplify the equation, we can start by evaluating the expressions on both sides. On the left-hand side, we have $2\left(-\frac{3}{9}\right)$ . To simplify this expression, we can multiply the number 2 by the fraction $-\frac{3}{9}$ . This gives us:

2\left(-\frac{3}{9}\right) = -\frac{6}{9}

On the right-hand side, we have $\left(-\frac{3}{9}\right)^2$ . To simplify this expression, we can square the fraction $-\frac{3}{9}$ . This gives us:

\left(-\frac{3}{9}\right)^2 = \frac{9}{81}

Evaluating the Equation

Now that we have simplified the expressions on both sides of the equation, we can evaluate the equation. We have:

-\frac{6}{9} = \frac{9}{81}

At first glance, this equation may seem to be false, but let's take a closer look. We can simplify the fraction on the right-hand side by dividing both the numerator and the denominator by their greatest common divisor, which is 9. This gives us:

\frac{9}{81} = \frac{1}{9}

The Property Illustrated by the Equation

Now that we have evaluated the equation, we can see that it is actually true. The equation $2\left(-\frac{3}{9}\right) = \left(-\frac{3}{9}\right)^2$ illustrates a fundamental property of algebra, which is the Inverse Property of Multiplication.

Conclusion

In conclusion, the equation $2\left(-\frac{3}{9}\right) = \left(-\frac{3}{9}\right)^2$ illustrates the Inverse Property of Multiplication. This property is essential in algebra because it allows us to simplify expressions and solve equations. By understanding this property, we can better appreciate the beauty and power of algebra and its applications in various fields of mathematics and science.
