How do you solve #log_10 7=log_10 x-log_10 2#?
For two logarithms of the same base,
Using the Quotient Law,
ABR May I suggest another approach:
Logs are indices in another form as such adding indices is another representation of multiplication. Like wise, subtraction is another representation of division. Consequently:
It is given that
( it does not matter a bout what the base is in this context)
From this it is a simple matter of manipulation to find
