a. (−3) 3 ÷ (−9) − 2 2 − (4 + 3 − 9) 3 − 5 × (−2) − 8 ÷ (22) × (−9 + 6)

b. −8 × (−4 + 3 − 2) + (−12) ÷ (3) + (−2 + 5)
c. (– 3 + 5 – 2 ) × (– 8 + 3 ) – (– 5 ) × (– 3 + 7 )

Answer 1

Explicación paso a paso:

a. (−3) 3 ÷ (−9) − 2 2 − (4 + 3 − 9) 3 − 5 × (−2) − 8 ÷ (22) × (−9 + 6)

-9÷(-9) - 22 - (-2)3 - (-10) - 8 ÷ (22) x (-3)

1 - 22 - (-6) + 10 - (8/22) x (-3)

1- 22 +6 +10 - 4/11 x (-3)

-21 + 16 + 12/11

-5+12/11

- 55/11 +12/11

-67/11

b. −8 × (−4 + 3 − 2) + (−12) ÷ (3) + (−2 + 5)

-8 x (-3) + (-4) + (3)
