me ajuda por favor ​

Answer 1

Resposta:

1-

a) 16/4 + 9 x 10 = 4 + 90 = 94

b) 36/(8+1) x (9-5) = 36/9 x 4 = 4 x 4 = 16

c) 49 + 2 x [(4)²- 4x1] = 49 + 2 x [16- 4] = 49 + 2 x [12] = 49 + 24 = 73

d) 25 + { 27/9 + [9x5 - 3x(8-5)] } = 25 + { 3 + [45 - 3x(3)] } =  25 + { 3 + [45 - 9] } =  25 + { 3 + 36 } = 25 + 39 = 64

2-

9 x [-9 + (-27)] / 9 = 9 x [36] / 9 = 324 / 9 = 36

b) + 36

3-

25/ -25 + [ 30 - ( - 10 + 6 ) ² / ( -8) - 25 ] =

-1 + [ 30 - ( -4 ) ² / ( -8) - 25 ] =

-1 + [ 30 - 16 / ( -8) - 25 ] =

-1 + [ 30 - 2 - 25 ] =

-1 + [ 3 ] =

-1 +3 = 2
