# How do you simplify 2x^3y^-3*2x^-1y^3 and write it using only positive exponents?

Oct 9, 2017

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

#### Explanation:

anything to a negative exponent means it's really $\frac{1}{\text{number}}$
therefore:
$\frac{2 {x}^{3}}{y} ^ 3 \cdot {y}^{3} / \left(2 x\right)$

Fractions multiply top$\times$top, bottom$\times$bottom

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