Simplify (x^3)^2 * X^3 And Find Y

Simplify the expression (x^3)^2 * x^3 and express it in the form x^y. What is the value of y?

In the realm of mathematics, simplifying expressions is a fundamental skill. This article focuses on simplifying an exponential expression and determining the value of an unknown exponent. Our main task is to simplify the expression $\left(x^3\right)2 \cdot x^3$ to the form $x^y$ and then find the value of $y$. Exponential expressions can seem daunting at first, but with a clear understanding of the rules of exponents, simplification becomes a straightforward process. Let’s embark on this mathematical journey, demystifying exponents and achieving a simplified solution.

Understanding the Basics of Exponents

Before diving into the simplification process, it’s essential to understand the fundamental rules of exponents. Exponents represent repeated multiplication, and there are specific rules that govern how they interact within mathematical expressions. Mastering these rules is crucial for efficiently simplifying expressions. Let’s delve into the key rules that we will apply in our simplification process:

1. Power of a Power Rule: When raising a power to another power, we multiply the exponents. Mathematically, this is expressed as $(a^m)n = a^{m \cdot n}$. This rule is crucial for simplifying expressions where an exponent is raised to another exponent. Understanding this rule allows us to condense complex expressions into simpler forms. When we encounter expressions like $\left(x^3\right)2$, this rule becomes our primary tool for simplification.

2. Product of Powers Rule: When multiplying expressions with the same base, we add the exponents. Mathematically, this is represented as $a^m \cdot a^n = a^{m + n}$. This rule allows us to combine terms with the same base, making the expression more concise. The product of powers rule is particularly useful when dealing with expressions involving multiple terms with the same base but different exponents. For instance, when we have $x^3 \cdot x^2$, this rule tells us to add the exponents, resulting in $x^5$.

These two rules form the cornerstone of simplifying exponential expressions. By applying these rules systematically, we can transform complex expressions into their simplest forms. A solid grasp of these rules not only aids in simplification but also enhances our overall understanding of algebraic manipulations. Let's proceed to apply these rules in simplifying the given expression.

Applying the Power of a Power Rule

To begin simplifying the expression $\left(x^3\right)2 \cdot x^3$, we first focus on the term $\left(x^3\right)2$. This is where the power of a power rule comes into play. As we discussed earlier, this rule states that when raising a power to another power, we multiply the exponents. Applying this rule to our term, we have:

$$\left(x^3\right)^2 = x^{3 \cdot 2} = x^6$$

By applying the power of a power rule, we have successfully simplified the term $\left(x^3\right)2$ to $x^6$. This step is crucial because it reduces the complexity of the expression and makes it easier to apply subsequent rules. The power of a power rule is a fundamental tool in simplifying exponential expressions, and mastering its application is essential for efficient problem-solving. This transformation allows us to rewrite our original expression as $x^6 \cdot x^3$, which is now ready for the next simplification step.

This intermediate step highlights the importance of breaking down complex problems into smaller, manageable parts. By focusing on simplifying one term at a time, we avoid confusion and ensure accuracy. The power of a power rule provides a clear and direct method for handling exponents raised to other exponents, making it an indispensable tool in our mathematical toolkit. Now, with the first term simplified, we move on to the next rule to further simplify the expression.

Applying the Product of Powers Rule

Now that we have simplified $\left(x^3\right)2$ to $x^6$, our expression looks like this: $x^6 \cdot x^3$. To further simplify this, we will use the product of powers rule. This rule states that when multiplying expressions with the same base, we add the exponents. In our case, the base is $x$, and the exponents are 6 and 3. Applying the product of powers rule, we get:

$$x^6 \cdot x^3 = x^{6 + 3} = x^9$$

By applying the product of powers rule, we have successfully combined the two terms into a single term with a simplified exponent. This rule is particularly useful because it allows us to condense multiple terms with the same base into a single term, making the expression much easier to handle. The product of powers rule is a cornerstone of exponential simplification, and its proper application leads to efficient solutions.

This step demonstrates the elegance and efficiency of the product of powers rule. By adding the exponents, we transform the expression into its simplest form. This simplification is not only mathematically correct but also provides a clear and concise representation of the original expression. With this rule, we can handle expressions involving multiple terms and reduce them to their fundamental components. Now that we have simplified the expression to the form $x^9$, we can easily identify the value of $y$.

Determining the Value of y

After simplifying the expression $\left(x^3\right)2 \cdot x^3$ using the rules of exponents, we arrived at the simplified form $x^9$. The problem states that this simplified expression is equal to $x^y$. Therefore, to find the value of $y$, we simply compare the exponents.

Comparing $x^9$ with $x^y$, it is clear that the exponents must be equal. Thus:

$$y = 9$$

So, the value of $y$ is 9. This final step underscores the importance of simplification in solving mathematical problems. By reducing the original expression to its simplest form, we made it straightforward to identify the value of the unknown exponent. Determining the value of $y$ completes our simplification process and provides a concrete answer to the problem.

This process illustrates the power of mathematical rules and how their systematic application can lead to clear and concise solutions. The ability to simplify expressions is a fundamental skill in mathematics, and by mastering the rules of exponents, we can confidently tackle a wide range of problems. The value of $y$ being 9 is the culmination of our step-by-step simplification, providing a definitive answer to the question.

Conclusion

In conclusion, we successfully simplified the expression $\left(x^3\right)2 \cdot x^3$ to the form $x^y$ and determined that the value of $y$ is 9. This process involved applying the power of a power rule and the product of powers rule. By understanding and applying these fundamental rules of exponents, we can simplify complex expressions efficiently. Simplifying exponential expressions is a crucial skill in mathematics, and mastering these rules will undoubtedly aid in tackling more advanced problems.

Through this step-by-step guide, we have demonstrated the importance of breaking down complex problems into smaller, manageable parts.
