take log to both sides :)
yeah thats it by taking log we will have (y-2)log8=log2+logy is it right ??? @Eyad
y= -1?
yes @annas thats right :)
is it maybe \[8^{y-2} =2^y\]??

okey dokey @Eyad
xD @annas.
yea satellite thats the equation
that would make life a lot easier. if it is \[8^{y-2}=2^y\] then since \(8=2^3\) you get \[2^{3y-6}=2^y\]making \[3y-6=y\] and then you can solve for y easily
2power y??? @tmest1992

you get \[3y-6=y\] \[2y=6\] \[y=3\]
gimmick is to write both sides with the same base
no the only power is (y-2)
ok if there is no power on 2 then it will be done by log method
