Question

Х Se consideră numerele: A = 16 + 6 x (6 + 6) - 3 (3 + 3) B = 136 - 3 x (3 + 27:9 3) C=37* 5+ (48: 6 + 14 x 3): 10. Calculează: 2 x (C-A + B). ​

Answer 1

Răspuns:

A = 16 + 6 x (6 + 6) - 3 (3 + 3)

A= 16 + 6×12-3×6

A= 16+72-18

A= 88-18

A= 70

B = 136 - 3 x (3 + 27:9)

B = 136 - 3× (3+3)

B = 136 - 3×6

B = 136 -18

B = 118

C=37*5+ (48: 6 + 14 x 3): 10

C= 185 + (8+42) : 10

C= 185 + 50:10

C= 185+5

C=190

2 x (C-A + B) = 2(190-70+118)

=2(120+118) = 2× 238

= 476
