Question

escreva 1/ 4- √3  e  1/ ³√4 , com denominadores racionalizados

Answer 1

$\boxed{ \frac{1}{4- \sqrt{3} } .\frac{4+ \sqrt{3} }{4+ \sqrt{3} }=\frac{4+ \sqrt{3} }{16-3}=\frac{4+ \sqrt{3} }{13}}\\ \\ \boxed{\frac{1}{ \sqrt[3]{4} }=\frac{1}{ \sqrt[3]{2^2} }.\frac{ \sqrt[3]{2} }{ \sqrt[3]{2} }=\frac{ \sqrt[3]{2} }{2}}$
