Question

Află suma a+b+c+d ştiind că :
a=4 236 ; b<a de 4 ori ; c=a+b : d>c de 4 ori Dau coroana ​

Answer 1

a=4.236

b=a:4 = 4.236 : 4 = 1.059

c= a+b = 4.236 + 1.059 = 5.295

d= c × 4 = 5.295 × 4 = 21.180

a+b+c+d = 4.236 + 1.059 + 5.295 + 21.180 = 31.770

Answer 2

a±b±c±d≈

a≈4236

b≈4236÷4≈1059

c≈1059±4236≈5295

d≈5295·4≈21180

21180±5295±1059±4236≈31770
