### How do you simplify logs?

It all depends on the problem. logs can be added or subtracted
if they have the same base. If not you must use a change of base
formula t convert them to the same base.
Use rules of logs after doing all the algebraic simplification
possible to convert the problem back to an algebra problem and
solve.
logb x + logb y = logb (xy) sum becomes a product
logb x - logb y = logb (x/y) difference becomes a quotient
a logb x = logb (xa) coefficicent becomes an exponent
rearrange the euation until there is only one log = a number or
one log = 2nd log
apply rules of inverse log ..... solve the problem
