d) [2x16:4+12:4x(24:6+2x100:100)]:(200:2:100)

Answer 1

Răspuns:

(0+124-124:4):[88:4+2x(44:4+22:2)-63]=

(0+124-31):[22+2x(11+11)-63]=

93:(22+2x22-63)=

93:(22+44-63)=

93:(66-63)=

93:3=31

90+[(45-34)x(56:8-7)]:10+3x(56-8x6)=

90+[11x(7-7)]:10+3x(56-48)=

90+(11x0):10+3x8

90+0:10+3x8=

90+0+24=114

49:7+[49+(48:3+36:9+7:7)]:10=

7+[49+(16+4+1)]:10=

7+(49+21):10=

7+70:10=

7+7=14

[2x16:4+12:4x(24:6+2x100:100)]:(200:2:100)=

[32:4+3x(4+200:100)]:(100:100)=

[8+3x(4+2)]:1=

(8+3x6):1=

(8+18):1=

26:1=26
