(ab²) × (−b²c) × (−a²c³) × (−3abc)

Answer 1

$$\begin{gathered} =(-3\times -1\times -1)\times (\mathrm{a}\times {\mathrm{a}}^2\times \mathrm{a}\times {\mathrm{b}}^2\times {\mathrm{b}}^2\times \mathrm{b}\times \mathrm{c}\times {\mathrm{c}}^3\times \mathrm{c} \\ =-3\times {\mathrm{a}}^{(1+2+1)}\times {\mathrm{b}}^{(2+2+1)}\times {\mathrm{c}}^{(1+4+1)} \\ =-3{\mathrm{a}}^4{\mathrm{b}}^5{\mathrm{c}}^5 \end{gathered}$$
