Question

Calcule:
X=
$(\frac{1}{3})^{5} \times ( \frac{1}{3})^{ - 3} \times ( \frac{1}{3})^{8} \div ( \frac{1}{3})^{9} =$
,calcule o valor de
${x}^{3}$

Answer 1

(1/3)^5 × (1/3)^(-3) × (1/3)^8 ÷ (1/3)^9 = x

x^3 = ???

(1/3)^(5+(-3)+8) ÷ (1/3)^9
(1/3)^10 ÷ (1/3)^9
(1/3)^(10-9)
(1/3)^1 = x

x^3 = (1/3)^3 = 1/27
