Introduction

Algebraic expressions can be complex and daunting, but with the right techniques and strategies, they can be simplified to reveal their underlying structure and meaning. In this article, we will focus on simplifying the expression $9w^{-9} \cdot 2v^{-9} \cdot 5v^{-4}x^4x^{-3}w$ . We will break down the expression into its constituent parts, apply the rules of exponents, and manipulate the terms to arrive at a simplified form.

Understanding Exponents

Before we dive into the simplification process, it's essential to understand the rules of exponents. Exponents are a shorthand way of representing repeated multiplication. For example, $a^3$ means $a \cdot a \cdot a$ . When we have multiple exponents with the same base, we can combine them by adding the exponents. For instance, $a^3 \cdot a^2 = a^{3+2} = a^5$ .

Simplifying the Expression

Now that we have a solid understanding of exponents, let's apply the rules to simplify the given expression. We will start by breaking down the expression into its constituent parts:

$9w^{-9} \cdot 2v^{-9} \cdot 5v^{-4}x^4x^{-3}w$

We can rewrite the expression as:

$9 \cdot 2 \cdot 5 \cdot w^{-9} \cdot v^{-9} \cdot v^{-4} \cdot x^4 \cdot x^{-3} \cdot w$

Applying the Rules of Exponents

Now that we have broken down the expression into its constituent parts, we can apply the rules of exponents to simplify it. We will start by combining the exponents with the same base:

$9 \cdot 2 \cdot 5 \cdot w^{-9} \cdot v^{-9} \cdot v^{-4} \cdot x^4 \cdot x^{-3} \cdot w$

Using the rule of exponents, we can combine the exponents with the same base:

$9 \cdot 2 \cdot 5 \cdot w^{-9+1} \cdot v^{-9-4} \cdot x^{4-3}$

Simplifying further, we get:

$90 \cdot w^{-8} \cdot v^{-13} \cdot x^1$

Simplifying Negative Exponents

We can simplify the negative exponents by rewriting them as positive exponents with the reciprocal of the base. For example, $w^{-8}$ can be rewritten as $\frac{1}{w^8}$ . Similarly, $v^{-13}$ can be rewritten as $\frac{1}{v^{13}}$ .

Applying this rule, we get:

$90 \cdot \frac{1}{w^8} \cdot \frac{1}{v^{13}} \cdot x^1$

Simplifying the Expression Further

We can simplify the expression further by combining the constants:

$90 \cdot \frac{1}{w^8} \cdot \frac{1}{v^{13}} \cdot x^1 = \frac{90x}{w^8v^{13}}$

Conclusion

In this article, we have simplified the expression $9w^{-9} \cdot 2v^{-9} \cdot 5v^{-4}x^4x^{-3}w$ using the rules of exponents. We have broken down the expression into its constituent parts, applied the rules of exponents, and manipulated the terms to arrive at a simplified form. The final simplified expression is $\frac{90x}{w^8v^{13}}$ .
