1/2 log x-log (5y)+log (7z)
write the given expression in condensed form
(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) ]
