b). 25 x [45 – (40 -10)] + 4 x (9+25)

c). {(54 + 18) ÷ 2+ (25-5) ÷ 4 } x 7

d). 62+ [53 – (9 x 5)] – 81 ÷9

Answer 1

Respuesta:

a) 76.(23+23)-4.(58-5) =

76.46-4.53 =

3496-212 = 3284

b) 25.(45-40-10)+4.(9+25) =

25.(45-30)+4.34 =

25.15+136 =

375+136 = 511

c) ((54+18):2+(25-5):4).7 =

(72:2+20:4).7 =

(36+5).7 =

41.7 = 287

d) 62+(53-9.5)-81:9 =

62+(53-45)-81:9 =

62+8-81:9 =

-11:9 = -1.2
