() (−5)³ ∙ (−2) − 3⁵ ( )-1
() 10 ∙ (−2)³– 3⁴ ( ) -20
Soluções para a tarefa
Resposta:A) 8 ∙ (−2) − (−36) ÷ (−9) (B)8
(B)(−15) ∙ 8 − (−2)⁷ (C)7
(C) (−5)³∙ (−2) − 3⁵ (D)-1
(D) 10 ∙ (−2)³ – 3⁴ (A)-20
Cálculos :
A) 8 ∙ (−2) − (−36) ÷ (−9) (C) (−5)³∙ (−2) − 3⁵ -16 - 4 = -20 -125 ∙ (−2) - 243
250-243 = 7
(B)(−15) ∙ 8 − (−2)⁷ (D) 10 ∙ (−2)³ – 3⁴
-120 + 128 = 8 10 ∙ (-8) - 81
-80 - 81 = -1
