Question

Efetue as operações indicadas

Answer 1

Explicação passo-a-passo:

a)

$\sqrt{12}+\sqrt{3}=\sqrt{4×3}+\sqrt{3}=2\sqrt{3}+\sqrt{3}=3\sqrt{3}$

b)

$\sqrt{50}+\sqrt{2}=\sqrt{25×2}+\sqrt{2}=5\sqrt{2}+\sqrt{2}=6\sqrt{2}$

c)

$\frac{\sqrt{49}}{\sqrt{25}}=\frac{7}{5}$

d)

$\frac{12\sqrt[3]{6}}{3\sqrt[3]{2}}=\frac{12\sqrt[3]{6}×\sqrt[3]{2^{2}}}{3\sqrt[3]{2}×\sqrt[3]{2^{2}}}=\frac{12\sqrt[3]{6×4}}{3×2}=2\sqrt[3]{24}$
