Question

e) [|-3²+(-3)³|-(-3) + (−2) · (5 - 7)]: (-3) =???
Ajutor!!!​

Answer 1

$\Big [|-3^{2} +(-3)^{3} |-(-3) + (-2) \cdot (5 - 7)\Big]: (-3) =$

$= \Big [|- 9 - 27 | + 3 + (- 2) \cdot (-2)\Big]: (-3)$

$= \Big (|- 36 | + 3 + 4\Big): (-3)$

$= \Big (36 + 7\Big): (-3)$

$= 43 : (-3)$

$= - 14\dfrac{1}{3}$

Answer 2

$\it [|-3^2+(-3)^3|-(-3)+(-2)\cdot(5-7)]:(-3)=[|-9-27|+3-2\cdot(-2)]:(-3)=\\ \\ =(36+3+4):(-3)=43:(-3)=-43:3$
