Question

1) Efetue as multiplicacoes;
a)raiz de 5 x raiz de 2
b)raiz quarta de 2 x raiz quarta de 8
c)raiz de 2 x (raiz de 7 + 2)

Answer 1

Resposta:

A)

$\sqrt{5} \times \sqrt{2} = \sqrt{10}$

B)

$\sqrt{2} \times \sqrt[4]{8} = 2 \sqrt[4]{2}$

C)

$\sqrt{2} \times \sqrt{7 + 2} = \sqrt{2} \times \sqrt{9} = \sqrt{2} \times 3 = 3 \sqrt{2}$
