For the given expression, use the associative property of multiplication to enter an equivalent expression.

(ab)c = ?

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:

y=20x

hope this
