Log*subscript*(3x − 2) 4096 = 3<br><br> I got x= negative 6 is this correct??
Brut [27]
Remember

log_a(b)=c translates to a^c=b
and
log_a(b^c)=clog_a(b)
so


4096=16^3
log_{3x-2}(4096)=3
log_{3x-2}(16^3)=3
3log_{3x-2}(16)=3
divide both sides by 3
log_{3x-2}(16)=1
translate
(3x-2)^1=16
3x-2=16
add 2 to both sides
3x=18
divide both sides by 3
x=6
