Vă rog cât de repede se poate!
Dau coroana!

Answer 1

$\star)2 \times [14 - 2 \times ( {3}^{2} - {2}^{3} )]$

$= 2 \times [14 - 2 \times (9 - 8)]$

$= 2 \times (14 - 2 \times 1)$

$= 2 \times (14 - 2)$

$= 2 \times 12$

$= 24$

$\star)2 \times (14 - 2) \times {3}^{2} - {2}^{3}$

$= 2 \times 12 \times 9 - 8$

$= 24 \times 9 - 8$

$= 216 - 8$

$= 208$

$\star)2 \times 14 - 2 \times ( {3}^{2} - {2}^{3} )$

$= 28 - 2 \times (9 - 8)$

$= 28 - 2 \times 1$

$= 28 - 2$

$= 26$
