Question 162960: The following questions are driving me crazy, please help!!!!!
1) Express as a single logarithm with a coefficient of 1. 2 In x -5 In y
2) Writh the logarithm in expanded form. log3(x^2y)3
The question donot come from a text book. My course is online and are questions posted by instructor.
I would be very appreciative if someone could help me solve these problems. I did not began to solve because I donot understand what is being asked.
Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
Your ability to solve these problems relies on your knowing the rules of logarithms!
"Product rule"
"Quotient rule"
"Power rule"
Now let's apply these to your problems:
1) First apply the "power rule" to get:
Now apply the "quotient tule" to get:

2) Rewrite this by expanding the argument of the logarithm
Now apply the "Product rule" to get:
Now you can apply the "Power rule" to get:
