(1/2)log x  - log (5y)  + log (7z)   =

 

We are using three properties here

 

a log b = log b^a

 

log a + log b=  log (ab)

 

log a + logb - log c  =    log [(ab)/c ]

 

So.....

 

log x^(1/2)  - log (5y) + log (7z)  =

 

log x^(1/2) + log (7z)  - log (5y)  =

 

log  √x  + log (7z) - log (5y)   =

 

log  [  ( 7z√x ) / ( 5y) ]

 

cool cool cool
