I assume you mean express x in terms of a,b,c, not logx.
logx = loga - log(b^2)
logx = log(a/b^2)
Then you can remove the log from each side (i.e. raise 10 to the power of each side). You get:
x = a/b^2
If logx=loga-2logb express log x in terms of a,b,c?
where is c??
log x = log a - log b^2
log x = log [a/b^2]
x = a/b^2
