Express as a equivalent logarithm: log (x-3)-8 log y +log 1.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You need to know that a) log(1) = 0; b) log(a) - log(b) = log() and c) n*log(a) = log().
Now let us apply it. You will get
log (x-3) - 8*log(y) + log(1) = log (x-3) - log() + 0 = log ().
That's all.
