Question

1) Efetue as divisões

A) (9x⁵y⁴z² + 15x³) : 3x³, com x ≠ 0

B) (36m³n⁵p + 45m⁵n³ - 27m⁹n³ - 27m⁹n⁷p³) : 9m³n², com m ≠ 0 e n ≠ 0

Answer 1

Explicação passo-a-passo:

a) $\frac{9x^{5}y^{4}z^{2}+15x^{3}}{3x^{3}}$

   $\frac{9x^{5}y^{4}z^{2}}{3x^{3}}+\frac{15x^{3}}{3x^{3}}$

   $(9:3.x^{5-3}.y^{4}.z^{2})+(15:3.x^{3-3})$

   $(3x^{2}y^{4}z^{2})+(5x^{0})$

   $3x^{2}y^{4}z^{2}+5$

b) $\frac{36m^{3}n^{5}p+45m^{5}n^{3}-27m^{9}n^{3}-27m^{9}n^{7}p^{3}}{9m^{3}n^{2}}$

   $\frac{36m^{3}n^{5}p}{9m^{3}n^{2}}+\frac{45m^{5}n^{3}}{9m^{3}n^{2}}-\frac{27m^{9}n^{3}}{9m^{3}n^{2}}-\frac{27m^{9}n^{7}p^{3}}{9m^{3}n^{2}}$

   $(36:9.m^{3-3}.n^{5-2}.p)+(45:9.m^{5-3}.n^{3-2})-(27:9.m^{9-3}.n^{3-2})-(27:9.m^{9-3}.n^{7-2}.p^{3})$

   $4m^{0}n^{3}p+5m^{2}n^{1}-3m^{6}n^{1}-3m^{6}n^{5}p^{3}$

   $4n^{3}p+5m^{2}n-3m^{6}n-3m^{6}n^{5}p^{3}$
