Okay, I thought this unit was easy not until Mr. K introduce the natural log. I think my muddiest point are the word problems especially the half-life ones. I get confuse which formula to use. Sometimes I make mistakes with using log or ln in solving for x. The change of base law is pretty easy and the one when you need to solve for x that was an exponent and they have to be in the same base. Good luck everyone!
