What is the true solution to the logarithmic equation below? log4[log4(2x]=1
x=2
x=8
x=65
x=128

1. 
write 1 as  so that we compare same base logarithms:



2. Neglect the equal bases and write the arguments:
 
So 

repeat step 1, that is write 4 as a logarithm with base 4: 

 

3. 

      
       
  

Hmmm i had this before , give me a sec
