Sorry, but #1 is confusing. What part goes inside of the radical?

The way to represent square root with the keyboard is: sqrt(x) which means . Everything you put inside of the parentheses is under the radical. The way you wrote your problem, I can't tell if you meant:



or



or



And you don't actually say what it is you want to do with this logarithm.

#2. Always put your log arguments in parentheses. I presume you meant:



I can only presume, because you didn't take the time to say, that you want to express this as a single logarithm.

First:



So



The difference of the logs is the log of the quotient, that is:



So:



Use the same rules for solving 3 as I showed you for 2 with the addition of the rule:

The sum of the logs is the log of the product:
