1. I don't know how to solve the equation : e^t/8 = 1000e^-t/8
2. Have you covered the addition rule for logarithms?

No prob
5. You could multiply through by to form a quadratic.
Then if you're unsure of what to do from there make the substitution .

In this case it isn't a quadratic.

Why not?

Why not?
Isn't that overcomplicating things? Can't you just multiply through by e^t/8 and take the natural log.

Well, yeah. That's what I'd do. But it's always good to know of alternate solutions.
