Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it requires a deep understanding of the underlying concepts. In this article, we will focus on simplifying a specific expression involving exponents and fractions. The given expression is (3a6b3)2−9a12b4\frac{\left(3 a^6 b^3\right)^2}{-9 a^{12} b^4}. Our goal is to simplify this expression by applying the rules of exponents and fractions.

Understanding Exponents

Before we dive into simplifying the expression, let's review the rules of exponents. When we have a power raised to another power, we multiply the exponents. For example, (am)n=amâ‹…n(a^m)^n = a^{m \cdot n}. This rule will be essential in simplifying the given expression.

Simplifying the Expression

To simplify the expression, we will start by applying the rule of exponents to the numerator. We have (3a6b3)2\left(3 a^6 b^3\right)^2, which can be rewritten as 32â‹…a6â‹…2â‹…b3â‹…23^2 \cdot a^{6 \cdot 2} \cdot b^{3 \cdot 2}. Using the rule of exponents, we get 9a12b69 a^{12} b^6.

Applying the Rule of Exponents to the Denominator

Now, let's focus on the denominator. We have −9a12b4-9 a^{12} b^4. We can rewrite this as −9⋅a12⋅b4-9 \cdot a^{12} \cdot b^4.

Simplifying the Fraction

Now that we have simplified the numerator and denominator, we can rewrite the expression as 9a12b6−9a12b4\frac{9 a^{12} b^6}{-9 a^{12} b^4}. To simplify this fraction, we can cancel out the common factors in the numerator and denominator. We have 99 in the numerator and −9-9 in the denominator, which can be canceled out. We also have a12a^{12} in both the numerator and denominator, which can be canceled out. Finally, we have b6b^6 in the numerator and b4b^4 in the denominator, which can be rewritten as b6−4b^{6-4}.

Final Simplification

After canceling out the common factors, we are left with b2−1\frac{b^2}{-1}. This can be rewritten as −b2-b^2.

Conclusion

In this article, we simplified the expression (3a6b3)2−9a12b4\frac{\left(3 a^6 b^3\right)^2}{-9 a^{12} b^4} by applying the rules of exponents and fractions. We started by simplifying the numerator and denominator separately, and then we canceled out the common factors to get the final simplified expression. The final simplified expression is −b2-b^2.
