f(g(x))
g(f(x))
Are f(x) and g(x) inverses of each other? Y/N

4x and 6y

im not sure though

ok thats very interesting

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

combine all like terms then its just a 2 step equation
