Math Problem Statement

Simplify the radical expression \(\sqrt[3]{\frac{x^3}{y^6}}\). Write your answer in the form \(A \sqrt[3]{B}\), or \(A^3 \sqrt[3]{B}\), where A and B are constants or expressions in x and y.

Solution

The given problem is to simplify the radical expression:

x3y63\sqrt[3]{\frac{x^3}{y^6}}

Step-by-step solution:

  1. Break the expression inside the cube root into parts: [ \sqrt[3]{\frac{x^3}{y^6}} = \frac{\sqrt[3]{x^3}}{\sqrt[3]{y^6}}. ]

  2. Simplify each term inside the cube root:

    • For x33\sqrt[3]{x^3}: The cube root of x3x^3 is xx.
    • For y63\sqrt[3]{y^6}: Use the rule ya3=ya/3\sqrt[3]{y^a} = y^{a/3}. So: y63=y6/3=y2.\sqrt[3]{y^6} = y^{6/3} = y^2.
  3. Combine the results: [ \frac{\sqrt[3]{x^3}}{\sqrt[3]{y^6}} = \frac{x}{y^2}. ]

Final Answer:

The simplified expression is: xy2\boxed{\frac{x}{y^2}}
