$\frac{a \cdot 2}{3} \cdot b^{- 3}$

Step 1

Move $2$ to the left of $a$ .

$\frac{2 \cdot a}{3} \cdot b^{- 3}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{2 a}{3} \cdot \frac{1}{b^{3}}$

Step 3

Combine.

$\frac{2 a \cdot 1}{3 b^{3}}$

Step 4

Multiply $2$ by $1$ .

$\frac{2 a}{3 b^{3}}$
