Important * means multiply (a) means base a etc
log(b)a*log(c)b*log(a)c=1

as you may know you can transform a logarithm, so you have only one base:
Your problem can be written like this:
Simplify the LHS of this equation and you'll get 1 = 1. Thus this equation is true for all
(Remark: The means union of 2 sets of numbers. )

Hello, kingkaisai2!
If you don't know the Base-Change Formula,
