Question

1. SIMPLIFIQUE AS SEGUINTES EXPRESSÕES:
b) X3 X5/
(x2)3
c) (a3 • b6)4/
ab2 e) (b/a3)-2 • (a3b/b-2)

Answer 1

b) $\frac{x^3.x^5}{(x^2)^3}=\frac{x^{3+5}}{x^{2.3}}=\frac{x^8}{x^6}=x^{8-6}=x^2$

c) $\frac{(a^3.b^6)^4}{ab^2}=\frac{a^{3.4}.b^{6.4}}{ab^2}=\frac{a^{12}.b^{24}}{ab^2}=a^{12-1}.b^{24-2}=a^{11}.b^{22}$

Answer 2

B) x²

c) a^11.b^22

e) a^9.b
