log(x) + log(y) = log(xy)
I haven't taken pre calc in 3 years so my memory of it is really sketchy..this is a review problem for calc which I'm taking right now.
Log(x^2+9x)=k
10^k=(x^2+9x)
Can't really figure out where to go from there. Like I said I barely remember anything from pre calc since its been about 3 years.
