Question

Ma ajutati va rog dau coroana​

Answer 1

Răspuns:

2^1994

Explicație pas cu pas:

2^(a+b)=2^a*2^b deci

2^(1994+1)=2^1994*2^1.........2^(1994+4)=2^1994*2^4

relatia devine

(2^1994*2^4+2^1994*2^3+2^1994*2^2+2^1994*2+2^1994):31

2^1994*(2^4+2^3+2^2+2+1):31=2^1994*(16+8+4+2+1):31=2^1994*31:31=2^1994
