    x2        
2/13   - 1 > 1

\left(\frac{2}{13}\right)^{x_{2}} - 1 > 1

(2/13)^x2 - 1 > 1

Rapid solution [src]

       log(2) 
x2 < ---------
     log(2/13)

x_{2} < \frac{\log{\left(2 \right)}}{\log{\left(\frac{2}{13} \right)}}

x2 < log(2)/log(2/13)

Rapid solution 2 [src]

        log(2)  
(-oo, ---------)
      log(2/13)
