Math Problem Statement

Simplify the radical expression: \(\sqrt[3]{8x^6}\). Write your answer in the form \(A\sqrt[3]{B}\), \(A^3\sqrt[3]{B}\), or \(A\), where \(A\) and \(B\) are constants or expressions in \(x\).

Solution

The problem requires simplifying the radical expression:
8x63.\sqrt[3]{8x^6}.

The answer should be written in the form AB3A \sqrt[3]{B}, A3B3A^3 \sqrt[3]{B}, or a similar form, where AA and BB are constants or expressions in xx.


Step-by-Step Solution:

  1. Break Down the Cube Root: [ \sqrt[3]{8x^6} = \sqrt[3]{8} \cdot \sqrt[3]{x^6}. ]

  2. Simplify Each Part:

    • 83=2\sqrt[3]{8} = 2, because 23=82^3 = 8.
    • x63=x2\sqrt[3]{x^6} = x^2, because x2x2x2=x6x^2 \cdot x^2 \cdot x^2 = x^6.

    So, the expression simplifies to: 2x2.2x^2.

  3. Final Answer: The simplified expression is: 2x2.2x^2.
