Question

The simplified form of $10\sqrt[3]{3x}-8\sqrt[3]{3x}$ is:

• A. $18\sqrt[3]{3x}$
• B. $2\sqrt{x}$
• C. $2\sqrt[3]{3x}$
• D. $18\sqrt{x}$

Answer 1

The correct option is C $2\sqrt[3]{3x}$

$10\sqrt[3]{3x}-8\sqrt[3]{3x}$ (like surds)

$=(10-8)\sqrt[3]{3x}=2\sqrt[3]{3x}$.

Hence, option $C$ is correct.
