Problem

The number

$\frac 2{\log_4{2000^6}} + \frac 3{\log_5{2000^6}}$

can be written as $\frac mn$ where $m$ and $n$ are relatively prime positive integers. Find $m + n$ .

Solution

$\frac 2{\log_4{2000^6}} + \frac 3{\log_5{2000^6}}=\frac{\log_4{16}}{\log_4{2000^6}}+\frac{\log_5{125}}{\log_5{2000^6}}=\log_{2000^6}{2000}=\frac{1}{6}$

$1+6=\boxed{007}$
