hello everyone, i am new here and plan to use this forum often, you guys seem very friendly. I am in college algebra right now and im having a huge problem with a few questions on my review packet for the exam coming up, the test is in a few days and these questions are going to be similar to the exam. i have been looking at my math book for the last 3-4 hours and i just cant find any similar questions, im stuck. very frustrated & stressed from this as well.

i scanned the math problem packet my teacher gave me to my pc, i mostly need help on "Express as a single logarithm" problems, they are the last 4 questions. but if you got extra time i would really appreciate it if you can help me on the top questions as well, but i know that might be asking to much so if anything just an answer to atleast one question from problems 11,12,13, or 14 would be great. thank you so much

here is the link of my problem packet, its a .jpg

if possible show your work to how you solved the problem, because i really would like to know how to do these. but if you cant i understand, it would be hard to type it out.

Thanks again everyone, this really is going to help me understand it a lot better.
