In general, when b is a positive integer ab

means to write a product with
as a factor
times.

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:

1.) 21

2.) 0.453

3.) 1.5

4.) 48

5.) $ 22
