Can't figure it out. I know that log base 2 24+log base 2 3 is the same as log base 2 72 but here it's minus so does it mean division?

log2 24 - log 2 3  = log5 x

 

Note that  the left side can be written as

 

log2 (24/3)  = log2 8  =  3

 

So  

 

3  =  log5 x

 

This says that   5^3  =  x  = 125

 

 

 

cool cool cool
