what does it mean to express in terms of sums 
and defferences of logartithms? 



Change the square root to the  power



Now you can move the  power out in front
of the log, like this



Now the log of a QUOTIENT equals the log of the 
numerator MINUS the log of the denominator



Now the log of a PRODUCT equals the log of the 
first factor  PLUS the log of the second factor .



Now you can move the 2 power out in front
of the log, like this



Now you can distribute the
