Question

. 2x2 302 - (1 240 : 4 x 3): 3 + 124 = (5 194 - 3 274) x 2 + 140 : (987 - 985) = 9 090 : 3 + 12x (785: 5 + 152) + 12 x 15 = 772 : 4 + 16 x (128 - 126: 9) = VA ROG​

Answer 1

Răspuns:

a) 4418

b) 3910

c) 6918

d) 2017

Explicație pas cu pas:

a) 2×2302-(1240:4×3):3+124= 4604-(310×3):3+124= 4604-310+124= 4728-310=4418

b) (5194-3274)×2+140:(987-985)= 1920×2+140:2= 3840+70=3910

c) 9090:3+12×(785:5+152)+12×15= 3030+12×(157+152)+180= 3030+12×309+180= 3030+3708+180= 6738+180=6918

d) 772:4+16×(128-126:9)= 193+16×(128-14)= 193+16×114= 193+1824= 2017
