Log(x-2) 16=log(2) 16 /log(2) (x-2)=4/log(2) (x-2); x-2>0; x≠3
log(x-2) 2=log(2) 2/log(2) (x-2)=1/log(2) (x-2)
тогда правая часть примет вид: log(x-2) 16 /log(x-2) 2=
=4/log(2) (x-2) :1/log(2) (x-2)=4
(log(3) x-3)^2=4
log(3) x -3=-2 ili log(3) x -3=2
log(3)x=1 log(3) x=5
x=3 посторонний x=3^5; x=243
