Question

(-12mnp).(-2m²n+5n³+3p³)

Answer 1

Oie, Td Bom?!

$= ( - 12mnp) \: . \: ( - 2m {}^{2} n + 5n {}^{3} + 3p {}^{3} )$

$= - 12mnp\: . \: ( - 2m {}^{2} n + 5n {}^{3} + 3p {}^{3} )$

$= - 12mnp \: . \: ( - 2m {}^{2} n) - 12mnp \: . \: 5n {}^{3} - 12mnp \: . \: 3p {}^{3}$

$= 24m {}^{3} n {}^{2} p - 60mn {}^{4} p - 36mnp {}^{4}$
