Just found this site and looks like it can be very helpful. I'm not asking for my homework to be done, I just have a few example problems I need help with, then I can figure it out on my own. I'm in an independant study type class where I learn the material on my own, and just take the test for each chapter to pass the class. Here are some problems I can use some help with:

---

Problem 1

---

log3 y = 1/2 log3 81

---

Problem 2

---

log6 (x+1) - log6 (x-1) = log6 9

---

Problem 3

---

log4 n = 2 log4 8

---

Problem 4

---

Use log4 7 = 1.4037 and log4 3 = 0.7925 to evaluate log 7/3

Example: log4 = log (subscript) 4

Thanks! I appreciate any help given!
