Question

Calcule os quocientes:
A)(15X^8):(-3X)
B)(-8X):(-8X)
C)(-14X^3):(+2X^2)
D)(-10X^3y):(+2Xy)
E)(-7abc):(-ab)​

Answer 1

Resposta:

$A)\\ \\ \frac{15x^{8} }{-3x} =\frac{15}{-3}.\frac{x^{8} }{x} =-5x^{7}$

$B)\\ \\ \frac{-8x}{-8x} =+1$

$C)\\ \\ \frac{-14x^{3} }{+2x^{2} } =\frac{-14}{2} .\frac{x^{3} }{x^{2} } =-7x^{3-2} =-7x^{1} =-7x$

$D)\\ \\ \frac{-10x^{3}y }{2xy} =\frac{-10}{2} .\frac{x^{3} }{x} .\frac{y}{y} =-5x^{2}$

$E)\\ \\ (-7abc:(-ab)=\frac{-7}{-1}.\frac{a}{a} .\frac{b}{b}.\frac{c}{1} =+7c$
