Question

Find the products:

$\left(\frac{-7}{5}{x}^{2}y\right)\times \left(\frac{3}{2}x{y}^2\right)\times \left(\frac{-6}{5}{x}^3{y}^3\right)$

Answer 1

$$\begin{gathered} =(\frac{-7}{5}\times \frac{3}{2}\times \frac{-6}{5})\times ({\mathrm{x}}^2\times \mathrm{x}\times {\mathrm{x}}^3\times \mathrm{y}\times {\mathrm{y}}^2\times {\mathrm{y}}^3) \\ =\frac{63}{25}\times {\mathrm{x}}^{(2+1+3)}\times {\mathrm{y}}^{(1+2+3)} \\ =\frac{63}{25}{\mathrm{x}}^6{\mathrm{y}}^6 \end{gathered}$$
