To effectively simplify the expression $(a^2)(2a^3)(a^2-8a+9)$, we need a firm grasp of two fundamental concepts: exponents and the distributive property. Exponents represent repeated multiplication. For instance, $a^2$ means $a$ multiplied by itself ($a imes a$), and $a^3$ means $a$ multiplied by itself three times ($a imes a imes a$). When multiplying terms with the same base, we add the exponents. This is known as the product of powers rule: $a^m imes a^n = a^{m+n}$. This rule is crucial for simplifying expressions involving variables raised to different powers. The distributive property, on the other hand, allows us to multiply a single term by a polynomial (an expression with multiple terms) by multiplying the term by each term within the polynomial. Mathematically, it is expressed as $a(b + c) = ab + ac$. This property is essential for expanding expressions and removing parentheses. In our given expression, we will use both the product of powers rule and the distributive property to simplify it. First, we'll multiply the terms with exponents, and then we'll distribute the resulting term across the polynomial. Understanding these concepts thoroughly will not only aid in simplifying this specific expression but also provide a solid foundation for more complex algebraic manipulations. Let’s now proceed to apply these principles step-by-step to our expression, ensuring a clear and methodical approach to simplification. We will break down each step to make it easy to follow and understand, ensuring that the underlying principles are well-illustrated and the process is transparent.

Let's begin the step-by-step simplification of the expression $(a^2)(2a^3)(a^2-8a+9)$. First, we'll focus on multiplying the terms with exponents: $(a^2)$ and $(2a^3)$. According to the product of powers rule, when multiplying terms with the same base, we add the exponents. So, $a^2 imes 2a^3$ can be simplified as follows: $a^2 imes 2a^3 = 2 imes (a^2 imes a^3) = 2 imes a^{2+3} = 2a^5$. Now we have simplified the first part of the expression to $2a^5$. Next, we need to multiply this result by the polynomial $(a^2-8a+9)$. This is where the distributive property comes into play. We will multiply $2a^5$ by each term in the polynomial: $2a^5(a^2-8a+9) = (2a^5 imes a^2) - (2a^5 imes 8a) + (2a^5 imes 9)$. Let’s simplify each term separately: $2a^5 imes a^2 = 2a^{5+2} = 2a^7$, $2a^5 imes 8a = 2 imes 8 imes a^{5+1} = 16a^6$, $2a^5 imes 9 = 2 imes 9 imes a^5 = 18a^5$. Now, we combine these simplified terms: $2a^7 - 16a^6 + 18a^5$. This is the simplified form of the original expression. Each step has been carefully broken down to illustrate the application of exponent rules and the distributive property. By following this methodical approach, we have successfully simplified a complex algebraic expression into a more manageable form. This process highlights the importance of understanding the underlying principles and applying them systematically to achieve accurate results.

To ensure complete clarity, let's provide a detailed breakdown of each step in simplifying the expression $(a^2)(2a^3)(a^2-8a+9)$. The initial step involves multiplying the first two terms: $(a^2)$ and $(2a^3)$. This requires applying the product of powers rule, which states that $a^m imes a^n = a^{m+n}$. So, we multiply the coefficients (1 and 2) and add the exponents of $a$: $a^2 imes 2a^3 = 1 imes 2 imes a^{2+3} = 2a^5$. This step condenses the first two terms into a single term, making the expression easier to handle. The next step is to distribute the term $2a^5$ across the polynomial $(a^2-8a+9)$. The distributive property dictates that we multiply $2a^5$ by each term inside the parentheses: $2a^5(a^2-8a+9) = (2a^5 imes a^2) - (2a^5 imes 8a) + (2a^5 imes 9)$. This step expands the expression, breaking it down into individual multiplications. Now, we simplify each term resulting from the distribution. For the first term, $2a^5 imes a^2$, we again use the product of powers rule: $2a^5 imes a^2 = 2a^{5+2} = 2a^7$. For the second term, $2a^5 imes 8a$, we multiply the coefficients and add the exponents: $2a^5 imes 8a = 2 imes 8 imes a^{5+1} = 16a^6$. For the third term, $2a^5 imes 9$, we simply multiply the coefficient: $2a^5 imes 9 = 2 imes 9 imes a^5 = 18a^5$. Finally, we combine the simplified terms: $2a^7 - 16a^6 + 18a^5$. This is the fully simplified form of the original expression. By meticulously breaking down each step and explaining the underlying principles, we have demonstrated how to simplify this algebraic expression. This detailed explanation should provide a clear understanding of the process and the rationale behind each step.
