$\frac{2 x}{x^{\frac{1}{3}} z^{- 3}}$

Step 1

Move $x^{\frac{1}{3}}$ to the numerator using the negative exponent rule $\frac{1}{b^{n}} = b^{- n}$ .

$\frac{2 x \cdot x^{- \frac{1}{3}}}{z^{- 3}}$

Step 2

Move $z^{- 3}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$2 x \cdot x^{- \frac{1}{3}} z^{3}$

Step 3

Multiply $x$ by $x^{- \frac{1}{3}}$ by adding the exponents.
