Deconstructing the Expression

To start, let's break down the given expression: x4y82124\sqrt[4]{\frac{x^4 y^8}{2^{12}}}. Our goal is to simplify this expression by applying the properties of radicals and exponents. The fourth root, denoted by the index 4, signifies that we are looking for factors that appear four times within the radicand (the expression inside the radical). We will carefully examine each component, including x4x^4, y8y^8, and 2122^{12}, and extract factors accordingly. We need to remember that taking an even root of a variable raised to an even power requires special attention, especially concerning absolute values. The variable x4x^4 inside the radical suggests that when we take the fourth root, we need to account for both positive and negative possibilities of xx, leading to the inclusion of an absolute value. In contrast, y8y^8 can be simplified without the need for absolute values, as the exponent is a multiple of the root index. Understanding these nuances is crucial to arrive at the correct simplified form. As we proceed, we'll address the exponent rules and radical properties that make this simplification possible.

Applying Radical Properties

The expression x4y82124\sqrt[4]{\frac{x^4 y^8}{2^{12}}} involves a fourth root of a fraction, which allows us to use the property abn=anbn\sqrt[n]{\frac{a}{b}} = \frac{\sqrt[n]{a}}{\sqrt[n]{b}}. Applying this property, we can rewrite the expression as x4y842124\frac{\sqrt[4]{x^4 y^8}}{\sqrt[4]{2^{12}}}. This separation helps us deal with the numerator and the denominator independently, making the simplification process more manageable. Now, let's focus on the numerator x4y84\sqrt[4]{x^4 y^8}. We can further separate this using the property abn=anâ‹…bn\sqrt[n]{ab} = \sqrt[n]{a} \cdot \sqrt[n]{b}, which gives us x44â‹…y84\sqrt[4]{x^4} \cdot \sqrt[4]{y^8}. Similarly, in the denominator, we have 2124\sqrt[4]{2^{12}}. Now, the task is to simplify each of these radical expressions individually.

For x44\sqrt[4]{x^4}, we must consider the absolute value because we are taking an even root of an even power. This means x44=∣x∣\sqrt[4]{x^4} = |x|. For y84\sqrt[4]{y^8}, we can rewrite y8y^8 as (y2)4(y^2)^4, so y84=y2\sqrt[4]{y^8} = y^2, and no absolute value is needed because squaring a real number always results in a non-negative value. For the denominator, 2124\sqrt[4]{2^{12}}, we can rewrite 2122^{12} as (23)4(2^3)^4, so 2124=23=8\sqrt[4]{2^{12}} = 2^3 = 8. Putting all these simplified terms together will give us the simplified form of the original expression. Understanding these transformations based on radical properties is key to reaching the final equivalent expression.

Simplifying the Numerator and Denominator

Now, let's simplify the numerator, x4y84\sqrt[4]{x^4 y^8}. We've already determined that x44=∣x∣\sqrt[4]{x^4} = |x|. This absolute value is crucial because the fourth root of x4x^4 must be non-negative, regardless of whether xx is positive or negative. Next, we consider y84\sqrt[4]{y^8}. To simplify this, we recognize that y8y^8 can be written as (y2)4(y^2)^4. Therefore, y84=(y2)44=y2\sqrt[4]{y^8} = \sqrt[4]{(y^2)^4} = y^2. Here, we don't need an absolute value because y2y^2 is always non-negative for any real number yy. Combining these, the simplified numerator becomes ∣x∣y2|x|y^2.

In the denominator, we have 2124\sqrt[4]{2^{12}}. We can rewrite 2122^{12} as (23)4(2^3)^4, which equals 848^4. Therefore, 2124=844=8\sqrt[4]{2^{12}} = \sqrt[4]{8^4} = 8. There's no need for an absolute value here since we're dealing with a positive number raised to a positive integer power.

Now, we have simplified the numerator to ∣x∣y2|x|y^2 and the denominator to 8. Putting these together, the simplified expression is ∣x∣y28\frac{|x|y^2}{8}. This expression clearly shows the relationship between xx, yy, and the constant term, revealing the equivalent form of the original expression.

Determining the Equivalent Expression

After simplifying the numerator and denominator separately, we can now put them together to find the equivalent expression. The simplified numerator is ∣x∣y2|x|y^2, and the simplified denominator is 8. Therefore, the equivalent expression for x4y82124\sqrt[4]{\frac{x^4 y^8}{2^{12}}} is ∣x∣y28\frac{|x|y^2}{8}. This result matches one of the given options, which confirms our calculations and simplification process.

By carefully applying the properties of radicals and exponents, we have successfully transformed the original complex expression into a simpler, equivalent form. This process highlights the importance of understanding how to handle even roots and absolute values, especially when dealing with variables. Our step-by-step approach ensures that each simplification is justified and clear, making the final result both understandable and reliable.

Conclusion: The Equivalent Expression is ∣x∣y28\frac{|x| y^2}{8}

In summary, we embarked on a journey to simplify the expression x4y82124\sqrt[4]{\frac{x^4 y^8}{2^{12}}}, and through a meticulous process of applying the properties of radicals and exponents, we successfully arrived at the equivalent form ∣x∣y28\frac{|x| y^2}{8}. The key steps included separating the radical of a fraction into the fraction of radicals, simplifying the numerator and denominator independently, and paying close attention to the absolute value when dealing with even roots of even powers.

This exercise underscores the significance of mastering algebraic manipulations and understanding the nuances of radicals and exponents. By carefully breaking down the problem into manageable parts and applying the appropriate rules, we were able to transform a seemingly complex expression into a clear and concise form. This not only enhances our mathematical problem-solving skills but also deepens our appreciation for the elegance and consistency of mathematical principles.
