Question

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

• A. $-\frac{1}{5}{x}^6{y}^{-}3$
• B. $-\frac{2}{7}{x}^2{y}^7$
• C. $-\frac{3}{5}{x}^3{y}^3$
• D. $-\frac{2}{5}{y}^3{x}^3$

Answer 1

Answer: (C)

$-\frac{3}{5}{x}^3{y}^3$

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