$2 x^{3} y^{- 3} \cdot 2 x^{- 1} y^{3}$

Step 1

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

$\frac{1}{y^{3}}$

Step 2

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

$\frac{1}{x}$

Step 3

Rewrite $2 x^{3} y^{- 3} \cdot (2 x^{- 1} y^{3})$ with positive exponents.

$2 x^{3} \frac{1}{y^{3}} \cdot 2 \frac{1}{x} y^{3}$
