Question

$\sqrt[2]{4} + \sqrt[2]{0.64} - \sqrt[2]{1.21}$ Calcule a raiz quadrada
​

Answer 1

Explicação passo-a-passo:

$= \sqrt{4} + \sqrt{0.64} - \sqrt{1.21}$

$= 2 + \sqrt{ \frac{64}{100} } - \sqrt{ \frac{121}{100} }$

$= 2 + \frac{ \sqrt{64} }{ \sqrt{100} } - \frac{ \sqrt{121} }{100}$

$= 2 + \frac{8}{10} + \frac{11}{10}$

$= 2 + 0.8 + 1.1$

$= 3.9$
