por favor ayudaa​

Answer 1

$-12.3+18:( -12:6+8)‐4²=$

$-36+\frac{18}{\frac{-2}{6}+8}-4^{2}$

$-36+\frac{18}{-\frac{1}{3}+8}-4^{2}$

$-36+\frac{18}{-\frac{1}{3}+\frac{24}{3}}-4^{2}$

$-36+\frac{18}{\frac{-1+24}{3}}-4^{2}$

$-36+\frac{18}{\frac{23}{3}}-4^{2}$

$-36+18\times \left(\frac{3}{23}\right)-4^{2}$

$-36+\frac{18\times 3}{23}-4^{2}$

$-\frac{828}{23}+\frac{54}{23}-4^{2}$

$\frac{-828+54}{23}-4^{2}$

$-\frac{774}{23}-4^{2}$

$-\frac{774}{23}-16$

$-\frac{774}{23}-\frac{368}{23}$

$-\frac{1142}{23}$
