-5-3-4•2=

-60-18+50=

(2+5•2)+(2-5•2)=

-7+6•3=

(4-3-2³)=

(6-3•4¹)=​

Answer 1

Resposta:

Explicação passo a passo:

1-Calcule

-5-3-4•2= -8-8= - 16

-60-18+50= -78+50= - 28

(2+5•2)+(2-5•2)= (2+10)+(2-10)

= 12-8

= 4

-7+6•3= -7+18= 11

(4-3-2³)= 1 - 8 = - 7

(6-3•4¹)=​ 6 - 3.4= 6-12= - 6

Answer 2

Vamos là.

a) -5 - 3 - 4*2 = -8 - 8 = -16

b) -60 - 18 + 50 = -78 + 50 = -28

c) (2 + 5*2) + (2- 5*2) = 2 + 10 + 2 - 10 = 4

d) -7 + 6*3 = 18 - 7 = 11

e) (4 - 3 - 8) = -11 + 4 = -7

f) (6 - 3*4^1) = 6 - 12 = -6
