Simplify








Solution:


 The strategy here is to rewrite everything in terms of powers of 3 and then use the inverse property of logs: 
log3%281%2F27%29%5E4=log3%28%281%2F3%5E3%29%29%5E4 

log3%28%281%2F3%5E3%29%29%5E4=log3%28%283%5E%28-3%29%29%29%5E4 

log3%28%283%5E%28-3%29%29%29%5E4=-12%2Alog3%283%29=-12
