Question

1) Calcule:

a) $\sqrt[2]{100}$

b) $\sqrt[3]{64}$

c) $\sqrt[2]{49}$

d) $\sqrt[3]{8}$

e) $\sqrt[3]{125}$

f) $\sqrt[4]{16}$

Answer 1

Explicação passo-a-passo:

$\sqrt[2]{100} = \sqrt[2]{10 {}^{2} } = 10 \\ \sqrt[3]{64} = \sqrt[3]{4 {}^{3} } = 4 \\ \sqrt[2]{49} = \sqrt[2]{7 {}^{2} } = 7 \\ \sqrt[3]{8} = \sqrt[3]{2 {}^{3} } = 2 \\ \sqrt[3]{125} = \sqrt[3]{5 {}^{3} } = 5 \\ \sqrt[4]{16} = \sqrt[4]{2 {}^{4} } = 2$
