This seemingly complex expression can be tamed by applying the fundamental principles of algebra and exponents. We'll break down each step, making it easy for you to follow along and master the simplification process. So, grab your mathematical tools, and let's dive in!

Demystifying Exponents: The Key to Simplification

Exponents, those little numbers perched atop variables and constants, hold the key to simplifying expressions like ours. Understanding the rules of exponents is crucial for navigating the mathematical landscape. Let's refresh our knowledge of some key exponent rules that we'll be using throughout this exploration:

• Product of Powers: When multiplying exponents with the same base, we add the powers. For instance, x^m * x^n = x^(m+n).
• Power of a Power: When raising a power to another power, we multiply the exponents. For example, (x^m)n = x^(m*n).
• Power of a Product: When raising a product to a power, we distribute the power to each factor within the product. For instance, (xy)^n = x^n * y^n.
• Negative Exponents: A negative exponent indicates the reciprocal of the base raised to the positive exponent. For example, x^(-n) = 1/x^n.
• Fractional Exponents: Fractional exponents represent roots. For instance, x^(1/n) is the nth root of x, and x^(m/n) is the nth root of x raised to the power of m.

With these exponent rules in our arsenal, we're well-equipped to tackle the simplification of our expression.

Breaking Down the Expression: A Step-by-Step Approach

Now, let's dissect the expression (x-1⁄3yz2⁄3)3 1/6)6 step by step. Our goal is to systematically apply the exponent rules to reduce the expression to its simplest form.

Step 1: Focus on the Innermost Exponents

We begin by addressing the exponents within the parentheses. Notice that we have terms with fractional exponents: x^(-1/3) and z^(2/3). These fractional exponents represent roots. Remember that x^(-1/3) is the same as 1/(x^(1/3)), which is the reciprocal of the cube root of x. Similarly, z^(2/3) represents the cube root of z squared.

Step 2: Apply the Power of a Product Rule

Next, we encounter the exponent outside the parentheses: 3. This exponent applies to the entire expression within the parentheses. Using the power of a product rule, we distribute this exponent to each factor inside the parentheses:

(x^(-1/3)yz(2/3))^3 = (x^(-1/3))3 * y^3 * (z^(2/3))3

Step 3: Apply the Power of a Power Rule

Now, we have exponents raised to other exponents. We can simplify these terms using the power of a power rule. Multiply the exponents:

• (x^(-1/3))3 = x^(-1/3 * 3) = x^(-1)
• (z^(2/3))3 = z^(2/3 * 3) = z^2

Substituting these simplified terms back into the expression, we get:

x^(-1) * y^3 * z^2

Step 4: Handle the Negative Exponent

We have a term with a negative exponent: x^(-1). To eliminate the negative exponent, we use the rule that x^(-n) = 1/x^n. Therefore, x^(-1) is the same as 1/x.

Substituting this back into the expression, we get:

(1/x) * y^3 * z^2

Step 5: Simplify the Expression

Finally, we can rewrite the expression in a more compact form:

y^3 * z^2 / x

Step 6: Address the Remaining Exponent

We still have the outer exponent of (1/6)6 to deal with. Let's simplify this first:

(1/6) * 6 = 1

So, the expression is now raised to the power of 1, which means it remains unchanged.

The Simplified Form: A Triumphant Conclusion

After meticulously applying the rules of exponents, we've successfully simplified the expression (x-1⁄3yz2⁄3)3 1/6)6 to its elegant form:

y^3 * z^2 / x

This simplified form is much easier to understand and work with than the original expression. We've transformed a seemingly complex expression into a clear and concise mathematical statement. Guys, wasn't that a rewarding journey?
