Hi fellas!
 
What happened to the log on procedure after you made these changes?  I kept trying to use my original name and password and couldn't get in.  Not only that, when I asked for the new info.from you  needed to get into my account it never came in my email!    I had to create another name and account.    I think you guys should look into this since I'm certain I'm not the only one who had problems.  Later!  

How to do a few log problems?
I have a few equations I need help with.
 
Simplify: e^4/e^3 x -3/e
 
Evaluate: log base 1/2 of 4
 
Solve: 10^3x+5 = 10^x-3
 
Find the inverse of the function y = log base 5 of x
 
If you could do it in steps, that'd be great! Thanks in advance.
