Question

Rezolvati:
a) 100-20:(35-4x8)
b) [(608+80:2)x5-55x3]x2
c) (912+164:2)-7x135
d) 4x[100:5+(175:5-50)]+303:3

Answer 1

a) 100 - 20 : (35 - 4 × 8) =

100 - 20 : (35 - 32) =

100 - 20 : 3 =

100 - 20/3 =

300/3 - 20/3 =

280/3 = 93,(3)

b) [(608 + 80 : 2) × 5 - 55 × 3] × 2 =

[(608 + 40) × 5 - 165] × 2 =

(648 × 5 - 165) × 2 =

(3240 - 165) × 2 =

3075 × 2 = 6150

c) (912 + 164 : 2) - 7 × 135 =

(912 + 82) - 945 =

994 - 945 = 49

d) 4 × [100 : 5 + (175 : 5 - 50)] + 303 : 3 =

4 × [20 + (35 - 50)] + 101 =

4 × (20 - 15) + 101 =

4 × 5 + 101 =

20 + 101 = 121
