Espero ter ajudado. :))

Answer 2

.
$\frac{2^{-1}+3^{-1}}{ \sqrt{1+5.4^{-1}} }=$

$\frac{ \frac{1}{2}+ \frac{1}{3} }{ \sqrt{1+5. \frac{1}{4} } } = \\ \\ \frac{ \frac{3+2}{6} }{ \sqrt{1+ \frac{5}{4} } } = \\ \\ \frac{ \frac{5}{6} }{ \sqrt{ \frac{4+5}{4} } } = \\ \\ \frac{ \frac{5}{6} }{ \sqrt{ \frac{9}{4} } } = \\ \\ \frac{5}{6} \div \frac{3}{2} = \frac{5}{6} \times \frac{2}{3} = \frac{10}{18} = \frac{5}{9}$

R: Letra C
