Are u sure the equation is correct ?

Answer 2

after the log the x-1 is small and then it's 16-4

Answer 3

\[\log_x-16=4\]?

Answer 4

Oh ,u mean Log(x-116)=4 ,or log(x) - 116=4

Answer 5

I guess it's like log(x-1)16-4

Answer 6

\[\log_{x-1}-16=4\]?

Answer 7

oh yeah I 'm sorry after the 16 it is an equal sign

Answer 8

if that,the answer is3 or-1

Answer 9

\[\log_{x-1}16=4\]\[4^{x-1}=16\]\[4^{x-1}=4^{2}\]\[x-1=2\]\[x=3\]
Why -1?\[4^{-2}={1\over16}\]
