Answer 1

Resposta:

Explicação passo-a-passo:

a) $\sqrt{2} . 7 = \sqrt{14}$

b) $\sqrt[3]{5.10} = \sqrt[3]{50}  =  \sqrt[3]{25.2}  = 5\sqrt[3]{2}$

c) $\sqrt[4]{6.2} = \sqrt[4]{12} = \sqrt[4]{4.3}  = 2\sqrt[4]{3}$

d) $\sqrt{15.2} = \sqrt{30}$

e) $\sqrt[3]{7.4}  = \sqrt[3]{28}$

f) $\sqrt{15:3} = \sqrt{5}$

g) $\sqrt[3]{20:2} = \sqrt[3]{10}$

h) $\sqrt[4]{15:5} = \sqrt[4]{3}$

i) $\sqrt{40:8} = \sqrt{5}$

j) $\sqrt[3]{30:10}  = \sqrt[3]{3}$
