How to solve an equation with e?

I don't know how to solve the equation : e^t/8 = 1000e^-t/8

Have you covered the addition rule for logarithms?

You could multiply through by e−t/8 e^{-t/8} to form a quadratic.
Then if you're unsure of what to do from there make the substitution u=et/8 u=e^{t/8} .

In this case it isn't a quadratic.

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. :yep:
