Respuestas
Respuesta:
A) 27 + 3 * 5 - 16 = 26
B) 27 +3 - 45 + 5 + 16 = -10
C) (2*4 +12) (6 - 4) = 40
D) 39 + (6 + 5 - 3) - 12 - 4 = - 8
E) 2 + 5*(23) = 117
F) 440 - [30 + 6 (19-12)] = 368
G) 2[4 ( 7 + 4(5*3-9)]- 3 (40 -8)= 152
Explicación paso a paso:
A) 27 + 3 * 5 - 16 = 27 + 15 - 16 = 26
B) 27 +3 - 45 + 5 + 16 = 30 - 45 + 5 + 16 = - 15 + 5 + 16 = - 10 + 16 = 6 = -10
C) (2*4 +12) (6 - 4) = (8 + 12) (6 - 4) = (20) (2) = 40
D) 39 + (6 + 5 - 3) - 12 - 4 = 39 + (6 + 2) - 12 - 4 = (8) - 12 - 4 = 8 - 16 = - 8
E) 2 + 5*(23) = 2 + 115 = 117
F) 440 - [30 + 6 (19-12)] = 440 - [30 + 6 (7)] = 440 - [30 + 42] = 440 - 72 = 368
G) 2[4 ( 7 + 4(5*3-9))]- 3 (40 -8) = 2[4 ( 7 + 4 (15-9))] - 3 (32) = 2[4 ( 7 + 4 (6))] - 96 = 2[4 ( 7 + 24)] - 96 = 2[4 (31)] - 96 = 2[124] - 96 = 248 - 96 = 152
