Question

como eu resolvo isso??

Answer 1

$a)\ \frac{1}{125^{ \frac{1}{3} }} = \frac{1}{ \sqrt[3]{125} } = \frac{1}{5} \\ \\ \\ b) \sqrt{1,1-0,46} =\sqrt{0,64} = \sqrt{ \frac{64}{100} }= \frac{ \sqrt{64}}{ \sqrt{100} } = \frac{8^{:2}}{10_{:2}} = \frac{4}{5}\\ \\b) \sqrt{1,1-0,46} =\sqrt{0,64} = \sqrt{ \frac{64}{100} }= \frac{ \sqrt{64}}{ \sqrt{100} } = \frac{8}{10} =0,8$
