Determina cifrele a si b pentru care: a)a5132=15b32,b)a5132 <15b32

Răspuns :

a) a5132 = 15b32

[tex]\it \overline{a5132} =\overline{15b32} \Longrightarrow a=1,\ \ b=1[/tex]

b) a5132 < 15b32

[tex]\it \overline{a5132} \ \textless \ \overline{15b32} \Longrightarrow a=1,\ \ b\in\{2,\ 3,\ 4,\ 5,\ 6,\ 7,\ 8,\ 9\}[/tex]
