Question

Find the product:
$\left(\frac{2}{3}xy\right)\times \left(\frac{-9}{10}{x}^2{y}^2\right)$

Answer 1

$\left(\frac{2}{3}xy\right)\times \left(\frac{-9}{10}{x}^2{y}^2\right)=(\frac{2}{3}\times \frac{-9}{10})(x\times x^{2}y\times y^2)=\frac{-18}{30}(x^{1+2}\times y^{1+2})=\frac{-3}{5}{x}^3{y}^3$
