Question

Simplify:$-12cd\times \frac{-4}{3}{c}^{2}d\times \frac{-15}{2}{c}^2{d}^2$

Answer 1

$-12cd\times \frac{-4}{3}{c}^{2}d\times \frac{-15}{2}{c}^2{d}^2$

$=(-12\times \frac{-4}{3}\times \frac{-15}{2})\times (c\times c^2\times c^2)\times (d\times d\times d^2)$

$=(-4\times -2\times -15)\times \left(c^{1+2+2}\right)\times \left(d^{1+1+2}\right)$

$=-120c^5{d}^4$
