Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}4*(\frac{1}{2})^4+(\frac{1}{4})^{\frac{1}{2}}=\\\\4*(\frac{1}{16}) + \frac{1}{2}= \\\\\frac{1}{4}+\frac{1}{2} = \\\\\frac{1+2}{4}=\\\\\ \boxed{\boxed{\frac{3}{4}}}\to Letra\ A\end{array}\right$

Espero ter ajudado. =^.^=

Answer 2

$4* ( \dfrac{1}{2})^4 + (\dfrac{1}{4})^\dfrac{1}{2}$

$4* ( \dfrac{1^4}{2^4}) + (\dfrac{1^\frac{1}{2}}{4^\frac{1}{2}}) } \\ \\ \\ 4* ( \dfrac{1}{16}) + (\dfrac{1}{2}) } \\ \\ \\ \dfrac{4}{16} + \dfrac{1}{2} \\ \\ \\ \dfrac{1}{4} + \dfrac{1}{2} \\ \\ \\ => \dfrac{3}{4}$


Resposta letra a) $\dfrac{3}{4}$
