:1001)]
DAU COROANA

Answer 1

Răspuns:

1)

a = [96 +70 x 100:( 19 x 2 + 395:79 + 243: 9)+4] :

(1000 - 999 )

a=[96+7000:(38+5+27)+4]:1

a=(96+7000:70+4):1

a=(96+100+4):1

a=200:1

a=200

b= 4195 - 4 x [2002 - (2002 - 2002 : 2 + 2002

:1001)]

b=4195-4x[2002-(2002-1001+2)]

b=4195-4x[2002-(1001+2)]

b=4195-4x(2002-1004)

b=4195-4x999

b=4195-3996

b=199

a:b

200:199=1 rest 1

{900-[(x:5+124x5x3:10):5+364]}-200x2x2:8=365

{900-[(x:5+620x3:10):5+364)]-400x2:8=365

{900-[(x:5+1860:10):5+364]}-800:8=365

{900-[(x:5+186):5+364]}-100=365

{900-[(x:5+186):5+364]}=365+100

900-[(x:5+186):5+364]=465

[(x:5+186):5+364]=900-465

(x:5+186):5+364=435

(x:5+186):5=435-364

(x:5+186):5=71

(x:5+186)=71x5

x:5+186=355

x:5=355-186

x:5=169

x=169x5

x=845
