e) (18-4.2).3 +2.3-32.(5-2) -
14.12: (10-2+8)] + 2 -

Answer 1

Resposta:

Explicação passo-a-passo:

a) (8:2). 4 + {[(32 - 2'). 2-5°). 4"}  = 4*4 + {(9-8) * (16-1)*4}  = 16 {1 * 15 * 4}  = 16 * 60 = 960

b) (3^2-2^3).3^3 -2^3 +2^4 . 4^2 =  (9-8) * 27 - 8 + 16 * 16 = 1 * 27 - 8 + 256 = 19 + 256 = 275

c) (2^5-3^3).(2^2-2) =  (32-27) * (2) = 5 * 2 = 10

d) {2. (10-4^2:2) + 6^2} :(2^3-2^2)  = {2 * (10-8) + 36 / 4} = 2 * 2 + 9 = 13

e) (18-4.2).3 +2^4.3-3^2.(5-2) = (18-8)*3 + 16*3 - 9*3 = 30 + 48 - 27 =  51

f) 4^2 . {2^4 : (10-2+8)] + 2^0 = 16 * (16/16) + 1 = 16* 1 + 1 = 17
