Answer 1

Răspuns:

a)23+7×{41+4×[3+8×(11×12-8×10)-59]}+1002=

23+7×{41+4×[3+8×(132-80)-59]}+1002=

23+7×[41+4×(3+8×52-59)]+1002=

23+7×[41+4×(3+416-59)]+1002=

23+7×[41+4×(419-59)]+1002=

23+7×(41+4×360)+1002=

23+7×(41+1440)+1002=

23+7×1481+1002=

23+10367+1002=

10390+1002=11392

b)(29×14-29×4)+12×11+8×{125-5×[340-2×(22×19-23×11)]}=

(406-116)+132+8×{125-5×[340-2×(418-253)]}=

290+132+8×[125-5×(340-2×165)]=

290+132+8×[125-5×(340-330)]=

290+132+8×(125-5×10)=

290+132+8×(125-50)=

290+132+8×75=

290+132+600=

422+600=1022

c)1+11×{1+11×[1+11×(11×11-120)]}+11×11=

1+11×{1+11×[1+11×(121-120)]}+121=

1+11×[1+11×(1+11×1)]+121=

1+11×[1+11×(1+11)]+121=

1+11×(1+11×12)+121=

1+11×(1+132)+121=

1+11×133+121=

1+1463+121=

1464+121=1585

d)[103-3×(21×11-23×9)]×{3+5×[2+3×(5+5×6)]}=

[103-3×(231-207)]×{3+5×[2+3×(5+30)]}=

(103-3×24)×[3+5×(2+3×35)]=

(103-72)×[3+5×(2+105)]=

31×(3+5×107)=

31×(3+535)=

31×538=16678
