Bonsouir cher ami !!

log3 5•log4 27•log25 √2. 
 
log 3 / log 5  *  log 27 / log 4  *  log √2./ log 25  


log 3/ log 5   *   log 3³ / log 2²   *  log  2^(1/2)  / log 5² 

log 3 / log 4   *   3 log 3 / 2 log 2   *   1/2 log 2   /  2 log 5 

Simplificando teremos :
   
  (1 * 3*1/2 )/( 1*2*-2  )   =   3/8    

A Bientot!!
