Iti rezolv 2 -3 exemple dupa care te descurci.Se folosesc formulele
log[a]x+log[a]y=log[a]x·y
log[a]x-log[a]y=log[a]x/y
k·log[a]x=log[a]x^k
Ex 1
log[a]x=log[a]3·4-log[a]5^4
log[a]x=log[a]12/5^4Delogaritmezi
x=12/625
_______________
a>0 ,a+b>0 ,a-b >0 a≠b
log[2]x=log[2]a²+log[2](a+b)³-log[2](a-b)^4
log[2]x=log[2]a²·(a+b)³/(a-b)^4
x=a²(a+b)³/(a-b)^4
