Question

5. Calcule os quocientes:

a) (21x⁶): (-7x⁴)

b) (-10a³):( (- 2 a²)​

Answer 1

Resposta:

$a)-3x^2\\b)5a$

Explicação passo-a-passo:

$21x^6/-7x^4\\\\Quociente=-3x^2\\Pois :-3x^2*-7x^4=21x^6\\Passa(-)=21x^6-21x^6=0=Resto\\\\-10a^3/-2a^2\\Quociente=5a\\Pois:5a*-2a^2=-10a^3\\Passa(+)=10a^3-10a^3=0=Resto$
