Some Basic Logarithims Questions!
Ok guys, just brushing up on some review questions and a few have stumped me. Appreciate it if you can help me out WITH HOW you solved the question. Thanks! Now the questions...
1)
**This one I thought was really easy but I got it wrong... So, If the base is the same (11), can't I just divide 64/16=4? Or, wait, can this be written as:

So would be my answer?
2) Simplify
as much as possible.
** This again is a difference question so I can rewrite this as a quotient and solve? Right track?
3) If write as a simple function of x.
** I suck at word problems or interpreting you can say. Kind of lost on this one but I am thinking, re write this as an exponential function? Not sure, just throwing it out there!
