Question

calcule os produtos:
A) m^2 . (m-n)
B) (6a^2+10ab+b^2) . (3/4a)
C)a^2b/2 . (b^2/3 - a^2/4)


^2= ao quadrado
VALENDO 35 PONTOS !!!!!!!

Answer 1

$a) \ m^2*(m-n)\\ m^3-m^2n\\\\ b) \ (6a^2+10ab+b^2)*( \frac{3}{4} a)\\\\ \frac{18}{4}a^3+ \frac{30}{4}a^2b+ \frac{3}{4}ab^2\\\\ \frac{9}{2}a^3+ \frac{15}{2}a^2b+ \frac{3}{4}ab^2\\\\ \frac{18a^3+30a^2b+3ab^2}{4} \\\\ c) \ \frac{a^2b}{2}*( \frac{b^2}{3} - \frac{a^2}{4} )\\\\ \frac{a^2b^3}{6} - \frac{a^4b}{12} \\\\ \frac{2a^2b^3-a^4b}{12}$
