e) 6xmai mic ca egal36
i)5x-11<34
m)2^xmai mic ca egal8
va rog imi trebuie urgenttttt!!!!!!!!!!!!!!!!!

Answer 1

x+3<4
x<4-3
x<1   deci sollutia este 0 fiindca 0+3=3<4

6x<=36
x<=6       solutii  (0,1,2,3,4,5,6)

5x-11<34
5x<34+11
5x<45
x<9         (solutii     0,1,2,3,4,6,7,8)

2^x<=8
2^3<=8   solutii(0,1,2,3,4,5,6,7,8)
