Quizplus · Accepted Answer

First, simplify each term: $4 \sqrt[3]{64x} = 4 \cdot 4 \sqrt[3]{x} = 16 \sqrt[3]{x}$ because $64x$ to the one-third power is $4x^{1/3}$, and $4 \sqrt[3]{8x} = 4 \cdot 2 \sqrt[3]{x} = 8 \sqrt[3]{x}$ because $8x$ to the one-third power is $2x^{1/3}$. Adding these together gives $16 \sqrt[3]{x} + 8 \sqrt[3]{x} = 24 \sqrt[3]{x}$.
