e)
$\sqrt[3]{4} . \sqrt[3]{6}$
b)
$\sqrt{2} . \sqrt{8}$
d)
$\sqrt{5} . \sqrt{10}$
​

Answer 1

Resposta:

$a) \sqrt[3]{5} \ . \ \sqrt[3]{6} =\sqrt[3]{5 \ . \ 6} =\sqrt[3]{30} \\\\c)\sqrt{2} \ . \ \sqrt{6} \ . \ \sqrt{3} =\sqrt{2 \ . \ 6 \ . \ 3} =\sqrt{36} =6\\\\e)\sqrt[3]{4} \ . \ \sqrt[3]{6} =\sqrt[3]{4 \ . \ 6} =\sqrt[3]{24} =\sqrt[3]{2^3 \ . \ 3} =\sqrt[3]{2^3} \sqrt[3]{3} =2\sqrt[3]{3}$

$b)\sqrt{2} \ . \ \sqrt{8} =\sqrt{2 \ . \ 8} =\sqrt{16} =4$

$d)\sqrt{5} \ . \ \sqrt{10} =\sqrt{5} \sqrt{5} \ . \ \sqrt{2} =5\sqrt{2}$
