Question

Utilize as propriedades dos radicais

Answer 1

$( \sqrt{19})^2 = 19$

$\sqrt{196*1,69} = \sqrt{169} * \sqrt{ \frac{169}{100} } = \sqrt{2^2.7^2} * \sqrt{ \frac{13^2}{10^2} } = 2.7 * \frac{13}{10} =14* \frac{13}{10}=$

$= \frac{182}{10} =18,2$

$\sqrt[3]{729} = \sqrt[3]{3^6} = 3^2 = 9$

$\sqrt[3]{ \frac{0,027}{1000} } = \sqrt[3]{ \frac{0,3^3}{10^3} } = \frac{0,3}{10} =0,03$
