### Son equasions esponensialis:3x+5=2; 2x-x+1=0;

Le equasion esponensial ax=bse a > 0, a ≠ 1 e b> 0, amet une e une sole solusion:-positive, se a e b e son entrambs magiors di 1, o entrambi minors di 1;-negative, se un dai doi numars a e b ale magior di 1 e l’atri ale minor di 1;-ugual a zero, se ale b=1 e a >0.

A chist punt o podin osservà che :le equasions esponensialis 3x=-3 e 1x=2non dan solusions, parsè 3x ale simpri positiv e 1x=1 par ogni x
