Question

Find the products:

$\left(\frac{-13}{5}a{b}^{2}c\right)\times \left(\frac{7}{3}{a}^{2}b{c}^2\right)$

Answer 1

$$\begin{gathered} =(\frac{-13}{5}\times \frac{7}{3})\times (\mathrm{a}\times {\mathrm{a}}^2\times {\mathrm{b}}^2\times \mathrm{b}\times \mathrm{c}\times {\mathrm{c}}^2) \\ =\frac{-91}{15}{\mathrm{a}}^{(1+2)}\times {\mathrm{b}}^{(2+1)}\times {\mathrm{c}}^{(1+2)} \\ =\frac{-91}{15}{\mathrm{a}}^3{\mathrm{b}}^3{\mathrm{c}}^3 \end{gathered}$$
