Question

Find the products:

$\left(\frac{-18}{5}{x}^{2}z\right)\times \left(\frac{-25}{6}x{z}^{2}y\right)$

Answer 1

$$\begin{gathered} =(-\frac{18}{5}\times \frac{-25}{6})\times ({\mathrm{x}}^2\times \mathrm{x}\times \mathrm{z}\times {\mathrm{z}}^2\times \mathrm{y}) \\ =15\times {\mathrm{x}}^{(2+1)}\times \mathrm{y}\times {\mathrm{z}}^{(1+2)} \\ =15{\mathrm{x}}^3{\mathrm{yz}}^3 \end{gathered}$$
