Understanding Logarithmic Function Problems: Solving for x

[feiser]

Homework Statement

solve x.
Log(35-x^3)/Log(5-x)=3

Homework Equations

Log(a/b)=Log a - Log b

The Attempt at a Solution

The answers would be 3 or 2
(so I'm guessing it has sumthing to do with quadratics)
i tried to expand the left side first, then rearrange it to Log(7/x^4)=3
the problem is that's not giving me the answer, which i got was 0.28925076.

The relevant equations you gave aren't necessary for the problem.
Move the Log(5-x) to the right hand side, then eliminate the logarithms. Then its just an algebra problem.
