Question

simplifique os radicais

​

Answer 1

a) $\sqrt{98}=\sqrt{7^2.2}=\sqrt{7^2}\sqrt{2}=7\sqrt{2}$

b) $\sqrt{27}=\sqrt{3^2.3}=\sqrt{3^2}\sqrt{3}=3\sqrt{3}$

c) $\sqrt[3]{729}=\sqrt[3]{9^3}=9$

d) $\sqrt{363}=\sqrt{11^2.3}=\sqrt{11^2}\sqrt{3}=11\sqrt{3}$

e) $\sqrt[3]{108}=\sqrt[3]{3^3.4}=\sqrt[3]{3^3}\sqrt[3]{4}=3\sqrt[3]{4}$

f) $\sqrt[5]{224}=\sqrt[5]{2^5.7}=\sqrt[5]{2^5}\sqrt[5]{7}=2\sqrt[5]{7}$

g) $\sqrt[4]{240}=\sqrt[4]{2^4.15}=\sqrt[4]{2^4}\sqrt[4]{15}=2\sqrt[4]{15}$
