Question

Calcule, usando as propriedades dos radicas aritméticos

$A) (\sqrt{10} )^{2} B) (\sqrt[3]{7} ) C) ( \sqrt[2]{8 ) ^{2} } D) ( \sqrt{3} ) ^{2}$

Answer 1

a) 10
$(\sqrt{10})^2 = \sqrt{10^2} = 10$

b) ∛7²
$(\sqrt[3]{7})^2 = \sqrt[3]{7^2}$

c) 8
$(\sqrt{8})^2 = \sqrt{8^2} = 8$

d) 3
$(\sqrt{3})^2 = \sqrt{3^2} = 3$
