Question

Porfavor eu preciso da resposta urgente ( tomara que entendam a fraçao)

3-efetue as divisões abaixo:

a) (2,5a^4 b - 4,5a^5b³) : (-5ab)

b)(1/6 x^4 y^4 - 5/8 x^3 y^3) : (1/2 x^3 y^3)

Answer 1

$a)2,5a^4b-4,5a^5b^3):(-5ab)=(25a^4b-45a^5b^3):(-50ab)= \\ \\ =-\frac{1}{2} a^3+ \frac{9}{10} a^4b^2 \\ \\ b)( \frac{1}{6} x^4y^4- \frac{5}{8} x^3y^3):(- \frac{1}{2} x^3y^3)=( \frac{1}{6}x^4y^4- \frac{5}{8} x^3y^3).( \frac{-2}{x^3y^3})= \\ \\= - \frac{1}{3} xy+ \frac{5}{4}$
