Question

Calcule os itens abaixo :

Answer 1

$a) \frac{1 + 4 -3}{4} = \frac{2}{4} = 0,5 \\ \\ b) \frac{3^3.3.3}{3^{ \frac{3}{2} }} = \frac{3^5}{3^{ \frac{3}{2} }} = 3^{5 - { \frac{3}{2} }} = 5^{{ \frac{7}{2} }} \\ \\ c) \frac{12.10}{12.10^{-5}} = 10^6 \\ \\ d)8^{0,6666...} = 8^{ \frac{2}{3}} = \sqrt[3]{8^2} = \sqrt[3]{64} = 4$
