    Radical exponets

    What is the cubic square root of 54?

    We know that you break down into 2*27, then 27 is equal to 3. What is not understood is three cubic root squared two.

\sqrt[3]{{54}} = \sqrt[3]{{2 \cdot 27}} = \sqrt[3]{2} \cdot \sqrt[3]{{27}} = 3\sqrt[3]{2}<br />

    I just want to make a quick note here to correct the terminology:
    \sqrt[3]{54} is simply called the "cube root" of 54. "Cubic square root" is a little misleading.
