Com resolução explicita!

Answer 1

√5 ≈ 2,24
∛2≈ 1,26

a) $\sqrt{3125}= \sqrt{5^2.5^2.5}=25 \sqrt{5}=25*2,24=56$

b) $\sqrt{180}= \sqrt{2^2.3^2.5}=6 \sqrt{5}=6*2,24=13,44$

c) $\sqrt[3]{128}= \sqrt[3]{2^3.2^3.2}=4 \sqrt[3]{2} =4*1,26=5,04$

d) $\sqrt[3]{432}= \sqrt[3]{2^3.2.3^3}=6 \sqrt[3]{2} = 6*1,26=7,56$
