help me ñ consigo entender ,AJUDE SE POSSÍVEL THANKSS...

Answer 1

2$^{-1}$ + 6 x (2/3)$^{-2}$ - (-1/3)$^{-1}$

$\frac{1}{2}$ + 6 x ($\frac{3}{2}$)$x^{2}$ - (-3)

$\frac{1}{2}$ + $\frac{12}{2}$ x ($\frac{9}{4}$) + 3

$\frac{1}{2}$ + $\frac{12}{2}$ x ($\frac{9}{4}$) + $\frac{6}{2}$

$\frac{1}{2}$ + $\frac{108}{8}$ + $\frac{6}{2}$

$\frac{1}{2}$ + $\frac{27}{2}$ + $\frac{6}{2}$ = $\frac{24}{2}$ = 12
