Answer

$\sqrt[3]{x^2}$

Work Step by Step

$$\sqrt[9]{x^6}$$ To convert from a radical expression to an expression with a rational exponent, the exponent becomes the numerator, and the index becomes the denominator: $$=x^\frac{6}{9}$$ Simplify all fractions: $$=x^\frac{2}{3}$$ Convert back to a radical expression - the numerator becomes the exponent, the denominator becomes the index: $$=\sqrt[3]{x^2}$$
