Introduction

Algebraic expressions are a fundamental concept in mathematics, and simplifying them is an essential skill for any math enthusiast. In this article, we will explore two algebraic expressions and simplify them using the division property of exponents. We will also discuss the importance of simplifying algebraic expressions and provide a step-by-step guide on how to do it.

The Division Property of Exponents

Before we dive into the simplification process, let's review the division property of exponents. The division property of exponents states that when we divide two exponential expressions with the same base, we can subtract the exponents. In other words, if we have two exponential expressions:

a^m \div a^n = a^{m-n}

where $a$ is the base and $m$ and $n$ are the exponents, then we can simplify the expression by subtracting the exponents.

Simplifying the First Expression

Let's simplify the first expression:

\left(15 p^8 q^9 - 30 p^7 q^{10} + 25 p^6 q^5\right) \div \left(5 p^3 q^4\right)

To simplify this expression, we need to divide each term in the numerator by the denominator. We can start by dividing the first term:

15 p^8 q^9 \div 5 p^3 q^4 = 3 p^5 q^5

Next, we can divide the second term:

-30 p^7 q^{10} \div 5 p^3 q^4 = -6 p^4 q^6

Finally, we can divide the third term:

25 p^6 q^5 \div 5 p^3 q^4 = 5 p^3 q^1

Now, we can combine the simplified terms:

3 p^5 q^5 - 6 p^4 q^6 + 5 p^3 q^1

Simplifying the Second Expression

Let's simplify the second expression:

\left(-6 s^5 t^9 - 54 s^4 t^8 + 18 s^3 t^6 - 24 s^2 t^3\right) \div \left(-6 s^3 t^2\right)

To simplify this expression, we need to divide each term in the numerator by the denominator. We can start by dividing the first term:

-6 s^5 t^9 \div -6 s^3 t^2 = s^2 t^7

Next, we can divide the second term:

-54 s^4 t^8 \div -6 s^3 t^2 = 9 s^1 t^6

Then, we can divide the third term:

18 s^3 t^6 \div -6 s^3 t^2 = -3 t^4

Finally, we can divide the fourth term:

-24 s^2 t^3 \div -6 s^3 t^2 = 4 s^{-1} t^1

Now, we can combine the simplified terms:

s^2 t^7 + 9 s^1 t^6 - 3 t^4 + 4 s^{-1} t^1
