Question

b) 27 - [15- (5 x 2 - 3) + 5)=
c) 5+{3+ [(7 x 3) + 41}=
d) 9+ [3 x(2 + 3) + 2 x (4 - 4)​

Answer 1

Resposta:

b) 27 - [15 - (5 × 2 - 3) + 5) =

27 - [15 - (10 - 3) + 5 ] =

27 - [15 - 7 + 5] =

27 - 13 =

14

c) 5 + {3 + (7 × 3) + 41} =

5 + {3 + 21 + 41} =

5 + {24 + 41} =

5 + 65 =

70

d) 9 + [3 × (2 + 3) + 2 × (4 - 4)] =

9 + [3 × 5 + 2 × 0] =

9 + [15 + 0] =

9 + 15 =

24
