Find integer values of $m$ and $n$ for which $m-n\log_32=10\log_96$.
I tried rewriting the RHS to $\log_3$ and the LHS to $\log_9$ but it seems that in each case I always miss something. I would really appreciate if someone could write a step-by-step solution.
$$10\log_96=5\log_36=5(1+\log_32).$$ Thus, $$m-5=(n+5)\log_32$$ and since $\log_32\not\in\mathbb Q,$ we obtain: $m=5$ and $n=-5$.
