Multiply and simplify. 5x^2 / y^3 * 4y^2 / 10x

Marta_Voda [28]

For this case we have the following expression:
$\frac{5x^2}{y^3} * \frac{4y^2}{10x}$
Rewriting the expression we have:
$\frac{20x^2y^2}{10xy^3}$
Then, simplifying and by properties of exponents we have:
${2x^{2-1}y^{2-3}} 

{2xy^{-1}}$
Rewriting we have::
$\frac{2x}{y}$
Answer:
The simplified expression is given by:
$\frac{2x}{y}$
