Question

Efetue as multiplicações e divisões e determine o valor​

Answer 1

Resposta:

a) $\sqrt{2} \times \sqrt{8} = \sqrt{2\times 8} = \sqrt{16} = 4$

b) $\sqrt[4]{2} \times \sqrt[4]{8} = \sqrt[4]{2 \times8} =\sqrt[4]{16} = \sqrt[2]{2^{4} } = 2$

c) $\dfrac{\sqrt[3]{16} }{\sqrt[3]{2} }= \sqrt[3]{\dfrac{16}{2} } = \sqrt[3]{8} =\sqrt[3]{2^{3} } = 2$

d) $\dfrac{\sqrt[3]{625} }{\sqrt[3]{5}} =\sqrt[3]{\dfrac{625}{5} } = \sqrt[3]{125} = \sqrt[3]{5 ^{2} } = 5$
