Juliette [100K]

18) Answer = $7m^8n^8$

$19m^8n^8-\left(4m^5n\right)\left(3m^3n^7\right)$

$=19m^8n^8-4m^5n\cdot \:3m^3n^7$

$=19m^8n^8-12m^8n^8$

$=7m^8n^8$

19) Answer = $c^5d^2$

$\left(-5cd\right)\left(-3c^4d\right)-\left(7c^2d^2\right)\left(2c^3\right)$

$=5cd\cdot \:3c^4d-7c^2d^2\cdot \:2c^3$

$=15c^5d^2-14c^5d^2$

$=c^5d^2$
