Answer 1

3 · ( -1/2)² - ($(1/2)^{-1}$1/2) + $(-1/4)^{-2}$
3 · 1/4  - 2 +16
3/4 + 14
3 + 56 /4
59/4

Answer 2

$3 * ( - \frac{1}{2})^2 - ( ( \frac{1}{2})^{-1}) + (- \frac{1}{4})^{-2} = \\ \\ 3 * ( - \frac{1}{2})^2 - ( ( 2)^{+1}) + (- {4})^{+2} = \\ \\ 3 * (+ \frac{1}{4}) - ( 2) + (16) = \\ \\ \frac{3}{4} - ( 2) + (16) = \frac{3-8+64}{4}= \boxed{ \frac{59}{4}}$
