Question

$\sqrt{0.04 + \sqrt{0.36} }$
​

Answer 1

Explicação passo-a-passo:

$\sqrt{0.04 + \sqrt{0.36}} = \\ \sqrt{ \frac{4}{100} + \sqrt{ \frac{36}{100} } } = \\ \sqrt{ \frac{1}{25} + \sqrt{ \frac{9}{25} } } = \\ \sqrt{ \frac{1}{25} + \frac{3}{5} } = \\ \sqrt{ \frac{5 + 75}{125} } = \sqrt{ \frac{80}{125} } = \\ \sqrt{ \frac{16}{25} } = \frac{4}{5}$
